Debian DLA-992-1 : eglibc security update (Stack Clash)

High Nessus Plugin ID 100875

Synopsis

The remote Debian host is missing a security update.

Description

The Qualys Research Labs discovered various problems in the dynamic linker of the GNU C Library which allow local privilege escalation by clashing the stack. For the full details, please refer to their advisory published at:
https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt

For Debian 7 'Wheezy', these problems have been fixed in version 2.13-38+deb7u12.

We recommend that you upgrade your eglibc packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
