CVE-2016-6323 (opens in a new tab)How to fix?
Upgrade Debian:8 glibc to version 2.19-18+deb8u6 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Debian.
See How to fix? for Debian:8 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.
