The GNU C Library security advisory update for 2026-03-30

[Siddhesh Poyarekar]

Hello,

The following security advisory has been published:

GLIBC-SA-2026-0007:
===================

iconv crash due to assertion failure with untrusted input

The iconv() function in the GNU C Library versions 2.43 and earlier may
crash due to an assertion failure when converting inputs from the
IBM1390 or IBM1399 character sets, which may be used to remotely crash
an application.

This vulnerability can be trivially mitigated by removing the IBM1390
and IBM1399 character sets from systems that do not need them.


Notes:
