CVE-2015-8778 (opens in a new tab)How to fix?
Upgrade RHEL:7 glibc-utils to version 0:2.17-196.el7 or higher.
This issue was patched in RHSA-2017:1916.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc-utils package and not the glibc-utils package as distributed by RHEL.
See How to fix? for RHEL:7 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.
