CVE-2016-6323 (opens in a new tab)How to fix?
Upgrade Ubuntu:14.04 eglibc to version 2.19-0ubuntu6.10 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream eglibc package and not the eglibc package as distributed by Ubuntu.
See How to fix? for Ubuntu:14.04 relevant fixed versions and status.
The makecontext function in the GNU C Library (aka glibc or libc6) before 2.25 creates execution contexts incompatible with the unwinder on ARM EABI (32-bit) platforms, which might allow context-dependent attackers to cause a denial of service (hang), as demonstrated by applications compiled using gccgo, related to backtrace generation.
