F5 Networks BIG-IP : GNU C Library (glibc) vulnerability (SOL16364)

Medium Nessus Plugin ID 82577

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc) 2.5, 2.12, and probably other versions does not 'properly restrict the use of' the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string using positional parameters and a large number of format specifiers, a different vulnerability than CVE-2012-3404 and CVE-2012-3405.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL16364.
