CVE-2015-8778 (opens in a new tab)How to fix?
Upgrade Debian:unstable glibc to version 2.21-8 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:unstable relevant fixed versions and status.
Integer overflow in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via the size argument to the __hcreate_r function, which triggers out-of-bounds heap-memory access.
