Debian DLA-494-1 : eglibc security update

Medium Nessus Plugin ID 91361

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities have been fixed in the Debian GNU C Library, eglibc :

CVE-2016-1234

Alexander Cherepanov discovered that the glibc's glob implementation suffered from a stack-based buffer overflow when it was called with the GLOB_ALTDIRFUNC flag and encountered a long file name.

CVE-2016-3075

The getnetbyname implementation in nss_dns was susceptible to a stack overflow and a crash if it was invoked on a very long name.

CVE-2016-3706

Michael Petlan reported that getaddrinfo copied large amounts of address data to the stack, possibly leading to a stack overflow. This complements the fix for CVE-2013-4458.

For Debian 7 'Wheezy', these problems have been fixed in version 2.13-38+deb7u11.

We recommend you to 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.
