Same as bug #23752. *** This bug has been marked as a duplicate of bug 23752 *** Thanks for paying attention to this problem and proposing to fix it in time. This bug was discovered by NTU Cyber-Security-Lab, for fuzzing research work. |
Hi there, Our fuzzer caught Invalid Address Read problem in eu-stack of the latest elfutils-0.174 code base, this inputs will cause the segment faults and I have confirmed them with address sanitizer too. Please use the "./eu-stack --core=$POC" or "./eu-stack --core=$POC -abdilmsv" to reproduce the bug. If you have any questions, please let me know. The ASAN dumps the stack trace as follows: ASAN:DEADLYSIGNAL ================================================================= ==9753==ERROR: AddressSanitizer: SEGV on unknown address 0x7f6afb9ac114 (pc 0x7f6afa17a7dc bp 0x7fffc8bb1900 sp 0x7fffc8bb17f0 T0) ==9753==The signal is caused by a READ memory access. #0 0x7f6afa17a7db in consider_notes /elfutils-0.174/libdwfl/dwfl_segment_report_module.c:486 #1 0x7f6afa17accc in consider_phdr /elfutils-0.174/libdwfl/dwfl_segment_report_module.c:529 #2 0x7f6afa176fa2 in dwfl_segment_report_module /elfutils-0.174/libdwfl/dwfl_segment_report_module.c:590 #3 0x7f6afa185ce0 in dwfl_core_file_report /elfutils-0.174/libdwfl/core-file.c:541 #4 0x405106 in parse_opt /elfutils-0.174/src/stack.c:590 #5 0x7f6af9a64847 in argp_parse (/lib/x86_64-linux-gnu/libc.so.6+0x114847) #6 0x4056a7 in main /elfutils-0.174/src/stack.c:690 #7 0x7f6af997082f in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x2082f) #8 0x402308 in _start (/elfutils-0.174/build/bin/eu-stack+0x402308) AddressSanitizer can not provide additional info.
