Description

Certain run-time memory protection mechanisms in the GNU C Library (aka glibc or libc6) print argv[0] and backtrace information, which might allow context-dependent attackers to obtain sensitive information from process memory by executing an incorrect program, as demonstrated by a setuid program that contains a stack-based buffer overflow error, related to the __fortify_fail function in debug/fortify_fail.c, and the __stack_chk_fail (aka stack protection) and __chk_fail (aka FORTIFY_SOURCE) implementations.

Affected products

• GNU C Library (glibc): before 2.26 — fixed in 2.26

How to fix

Upgrade to a fixed version: GNU C Library (glibc) 2.26. Check the vendor advisory for mitigations.
