The following testcase passes a value slightly smaller than 1.0 to frexpl, which ought to be returned unchanged with expon set to zero. Instead we get a value slightly smaller than 0.5 with expon set to one. #include <stdio.h> #include <math.h> int main(void) { union { long double ld; double d[2]; int i[4]; long long l[2]; } x; int expon; x.d[0] = 0x1p0; x.d[1] = -0x1p-106; printf ("%La %13a %13a 0x%16llx 0x%16llx\n", x.ld, x.d[0], x.d[1], x.l[0], x.l[1]); x.ld = frexpl (x.ld, &expon); printf ("%La %13a %13a 0x%16llx 0x%16llx\n", x.ld, x.d[0], x.d[1], x.l[0], x.l[1]); printf ("expon = %d\n", expon); return 0; }

The function wordexp() fails to properly handle the WRDE_NOCMD flag when processing arithmetic inputs in the form of "$((... ``))" where "..." can be anything valid. The backticks in the arithmetic epxression are evaluated by in a shell even if WRDE_NOCMD forbade command substitution. This allows an attacker to attempt to pass dangerous commands via constructs of the above form, and bypass the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD in exec_comm(), the only place that can execute a shell. All other checks for WRDE_NOCMD are superfluous and removed. We expand the testsuite and add 3 new regression tests of roughly the same form but with a couple of nested levels. On top of the 3 new tests we add fork validation to the WRDE_NOCMD testing. If any forks are detected during the execution of a wordexp() call with WRDE_NOCMD, the test is marked as failed. This is slightly heuristic since vfork might be used in the future, but it provides a higher level of assurance that no shells were executed as part of command substitution with WRDE_NOCMD in effect. In addition it doesn't require libpthread or libdl, instead we use the public implementation namespace function __register_atfork (already part of the public ABI for libpthread). Tested on x86_64 with no regressions. https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=32404a33a03747951daafde164e3b14464c28fe9 commit 32404a33a03747951daafde164e3b14464c28fe9 Author: Allan McRae <allan@archlinux.org> Date: Thu Dec 18 11:01:43 2014 +1000 Label CVE-2014-9402 in NEWS https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=d2a6f3a27b791d91beec2ea91f293ec898080904 commit d2a6f3a27b791d91beec2ea91f293ec898080904 Author: Florian Weimer <fweimer@redhat.com> Date: Mon Dec 15 17:41:13 2014 +0100 Avoid infinite loop in nss_dns getnetbyname [BZ #17630] https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=39700792d4224af99ab52ea26e98a0a2a2ed6ac6 commit 39700792d4224af99ab52ea26e98a0a2a2ed6ac6 Author: Jeff Law <law@redhat.com> Date: Mon Dec 15 10:09:32 2014 +0100 CVE-2012-3406: Stack overflow in vfprintf [BZ #16617] A larger number of format specifiers coudld cause a stack overflow, potentially allowing to bypass _FORTIFY_SOURCE format string protection. https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=5cefe3fc8f35b50eb84cbb740268539a40651173 commit 5cefe3fc8f35b50eb84cbb740268539a40651173 Author: Allan McRae <allan@archlinux.org> Date: Sat Jun 21 17:23:55 2014 +1000 Mention CVE-2014-4043 in NEWS https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=eece504424b59a1d8de7b4da9c64e24acaa6fbe0 commit eece504424b59a1d8de7b4da9c64e24acaa6fbe0 Author: Florian Weimer <fweimer@redhat.com> Date: Wed Jun 11 23:12:52 2014 +0200 posix_spawn_file_actions_addopen needs to copy the path argument (BZ 17048) POSIX requires that we make a copy, so we allocate a new string and free it in posix_spawn_file_actions_destroy.

Basically the idea is to use the memcpy for POWER7 on non-overlapped memory regions and a optimized backward memcpy for memory regions that overlap (similar to the idea of string/memmove.c). The backward memcpy algorithm used is similar the one use for memcpy for POWER7, with adjustments done for alignment.

The GNU C Library webpage is at http://www.gnu.org/software/libc/ Packages for the 2.21 release may be downloaded from: http://ftpmirror.gnu.org/libc/ http://ftp.gnu.org/gnu/libc/ The mirror list is at http://www.gnu.org/order/ftp.html NEWS for version 2.21 ===================== * The following bugs are resolved with this release: 6652, 10672, 12674, 12847, 12926, 13862, 14132, 14138, 14171, 14498, 15215, 15378, 15884, 16009, 16418, 16191, 16469, 16576, 16617, 16618, 16619, 16657, 16740, 16857, 17192, 17266, 17273, 17344, 17363, 17370, 17371, 17411, 17460, 17475, 17485, 17501, 17506, 17508, 17522, 17555, 17570, 17571, 17572, 17573, 17574, 17582, 17583, 17584, 17585, 17589, 17594, 17601, 17608, 17616, 17625, 17630, 17633, 17634, 17635, 17647, 17653, 17657, 17658, 17664, 17665, 17668, 17682, 17702, 17717, 17719, 17722, 17723, 17724, 17725, 17732, 17733, 17744, 17745, 17746, 17747, 17748, 17775, 17777, 17780, 17781, 17782, 17791, 17793, 17796, 17797, 17801, 17803, 17806, 17834, 17844, 17848, 17868, 17869, 17870, 17885, 17892. * CVE-2015-1472 Under certain conditions wscanf can allocate too little memory for the to-be-scanned arguments and overflow the allocated buffer. The implementation now correctly computes the required buffer size when using malloc. * A new semaphore algorithm has been implemented in generic C code for all machines. Previous custom assembly implementations of semaphore were difficult to reason about or ensure that they were safe. The new version of semaphore supports machines with 64-bit or 32-bit atomic operations. The new semaphore algorithm is used by sem_init, sem_open, sem_post, sem_wait, sem_timedwait, sem_trywait, and sem_getvalue. * Port to Altera Nios II has been contributed by Mentor Graphics. * Optimized strcpy, stpcpy, strncpy, stpncpy, strcmp, and strncmp implementations for powerpc64/powerpc64le. Implemented by Adhemerval Zanella (IBM). * Added support for TSX lock elision of pthread mutexes on powerpc32, powerpc64 and powerpc64le. This may improve lock scaling of existing programs on HTM capable systems. The lock elision code is only enabled with --enable-lock-elision=yes. Also, the TSX lock elision implementation for powerpc will issue a transaction abort on every syscall to avoid side effects being visible outside transactions. * Optimized strcpy, stpcpy, strchrnul and strrchr implementations for AArch64. Contributed by ARM Ltd. * i386 memcpy functions optimized with SSE2 unaligned load/store. * CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag under certain input conditions resulting in the execution of a shell for command substitution when the applicaiton did not request it. The implementation now checks WRDE_NOCMD immediately before executing the shell and returns the error WRDE_CMDSUB as expected. * CVE-2012-3406 printf-style functions could run into a stack overflow when processing format strings with a large number of format specifiers. * CVE-2014-9402 The nss_dns implementation of getnetbyname could run into an infinite loop if the DNS response contained a PTR record of an unexpected format. * The minimum GCC version that can be used to build this version of the GNU C Library is GCC 4.6. Older GCC versions, and non-GNU compilers, can still be used to compile programs using the GNU C Library. * The GNU C Library is now built with -Werror by default. This can be disabled by configuring with --disable-werror. * New locales: tu_IN, bh_IN, raj_IN, ce_RU. * The obsolete sigvec function has been removed. This was the original 4.2BSD interface that inspired the POSIX.1 sigaction interface, which programs have been using instead for about 25 years. Of course, ABI compatibility for old binaries using sigvec remains intact. * Merged gettext 0.19.3 into the intl subdirectory. This fixes building with newer versions of bison. * Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions. The original MIPS o32 hard-float ABI requires an FPU where double-precision registers overlay two consecutive single-precision registers. MIPS32R2 introduced a new FPU mode (FR=1) where double-precision registers extend the corresponding single-precision registers which is incompatible with the o32 hard-float ABI. The MIPS SIMD ASE and the MIPSR6 architecture both require the use of FR=1 making a transition necessary. New o32 ABI extensions enable users to migrate over time from the original o32 ABI through to the updated o32 FP64 ABI. To achieve this the dynamic linker now tracks the ABI of any loaded object and verifies that new objects are compatible. Mode transitions will also be requested as required and unsupportable objects will be rejected. The ABI checks include both soft and hard float ABIs for o32, n32 and n64. GCC 5 with GNU binutils 2.25 onwards: It is strongly recommended that all o32 system libraries are built using the new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible with the original and all new o32 ABI extensions. Configure a MIPS GCC compiler using --with-fp-32=xx to set this by default. Contributors ============ This release was made possible by the contributions of many people.

The implementation now correctly computes the required buffer size when using malloc. A regression test was added to tst-sscanf. Conflicts: ChangeLog NEWS https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=88a8a351f3a6a95205a1499fd68b79fc3d0b9d19 commit 88a8a351f3a6a95205a1499fd68b79fc3d0b9d19 Author: Carlos O'Donell <carlos@redhat.com> Date: Wed Nov 19 11:44:12 2014 -0500 CVE-2014-7817: wordexp fails to honour WRDE_NOCMD. The function wordexp() fails to properly handle the WRDE_NOCMD flag when processing arithmetic inputs in the form of "$((... ``))" where "..." can be anything valid. The backticks in the arithmetic epxression are evaluated by in a shell even if WRDE_NOCMD forbade command substitution. This allows an attacker to attempt to pass dangerous commands via constructs of the above form, and bypass the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD in exec_comm(), the only place that can execute a shell. All other checks for WRDE_NOCMD are superfluous and removed. We expand the testsuite and add 3 new regression tests of roughly the same form but with a couple of nested levels. On top of the 3 new tests we add fork validation to the WRDE_NOCMD testing. If any forks are detected during the execution of a wordexp() call with WRDE_NOCMD, the test is marked as failed. This is slightly heuristic since vfork might be used in the future, but it provides a higher level of assurance that no shells were executed as part of command substitution with WRDE_NOCMD in effect. In addition it doesn't require libpthread or libdl, instead we use the public implementation namespace function __register_atfork (already part of the public ABI for libpthread). Tested on x86_64 with no regressions. https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=32404a33a03747951daafde164e3b14464c28fe9 commit 32404a33a03747951daafde164e3b14464c28fe9 Author: Allan McRae <allan@archlinux.org> Date: Thu Dec 18 11:01:43 2014 +1000 Label CVE-2014-9402 in NEWS https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=d2a6f3a27b791d91beec2ea91f293ec898080904 commit d2a6f3a27b791d91beec2ea91f293ec898080904 Author: Florian Weimer <fweimer@redhat.com> Date: Mon Dec 15 17:41:13 2014 +0100 Avoid infinite loop in nss_dns getnetbyname [BZ #17630] https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=39700792d4224af99ab52ea26e98a0a2a2ed6ac6 commit 39700792d4224af99ab52ea26e98a0a2a2ed6ac6 Author: Jeff Law <law@redhat.com> Date: Mon Dec 15 10:09:32 2014 +0100 CVE-2012-3406: Stack overflow in vfprintf [BZ #16617] A larger number of format specifiers coudld cause a stack overflow, potentially allowing to bypass _FORTIFY_SOURCE format string protection. https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=5cefe3fc8f35b50eb84cbb740268539a40651173 commit 5cefe3fc8f35b50eb84cbb740268539a40651173 Author: Allan McRae <allan@archlinux.org> Date: Sat Jun 21 17:23:55 2014 +1000 Mention CVE-2014-4043 in NEWS https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=eece504424b59a1d8de7b4da9c64e24acaa6fbe0 commit eece504424b59a1d8de7b4da9c64e24acaa6fbe0 Author: Florian Weimer <fweimer@redhat.com> Date: Wed Jun 11 23:12:52 2014 +0200 posix_spawn_file_actions_addopen needs to copy the path argument (BZ 17048) POSIX requires that we make a copy, so we allocate a new string and free it in posix_spawn_file_actions_destroy.

Basically the idea is to use the memcpy for POWER7 on non-overlapped memory regions and a optimized backward memcpy for memory regions that overlap (similar to the idea of string/memmove.c). The backward memcpy algorithm used is similar the one use for memcpy for POWER7, with adjustments done for alignment. The difference is memory is always aligned to 16 bytes before using VSX/altivec instructions. https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=dde00e9914370ddd90c9bbc4f3f0e455efae4b47 commit dde00e9914370ddd90c9bbc4f3f0e455efae4b47 Author: Adhemerval Zanella <azanella@linux.vnet.ibm.com> Date: Tue Jun 24 06:42:31 2014 -0500 PowerPC: memmove default implementation cleanup This patch removes the powerpc specific logic in memmove and instead include default implementation with MEMCPY_OK_FOR_FWD_MEMMOVE defined. This lead in a increase performance, since the constraints to use memcpy in powerpc code are too restrictive and memcpy can be used for any forward memmove.

The ldbl-128ibm implementation of ilogbl produces incorrect results when the high part of the argument is a power of 2 and the low part a nonzero number with the opposite sign (and so the returned exponent should be 1 less than that of the high part). For example, ilogbl (0x1.ffffffffffffffp1L) returns 2 but should return 1. (This is similar to (fixed) bug 16740 for frexpl, and bug 18030 for logbl.) This patch adds checks for that case. Tested for powerpc. [BZ #18029] * sysdeps/ieee754/ldbl-128ibm/e_ilogbl.c (__ieee754_ilogbl): Adjust exponent of power of 2 down when low part has opposite sign. * math/libm-test.inc (ilogb_test_data): Add more tests. ----------------------------------------------------------------------- Summary of changes: ChangeLog | 8 ++++++++ NEWS | 2 +- math/libm-test.inc | 5 +++++ sysdeps/ieee754/ldbl-128ibm/e_ilogbl.c | 23 +++++++++++++++++++---- 4 files changed, 33 insertions(+), 5 deletions(-)
