Debian DLA-350-1 : eglibc security update

high Nessus Plugin ID 87071

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The strxfrm() function is vulnerable to integer overflows when computing memory allocation sizes (similar to CVE-2012-4412).
Furthermore since it fallbacks to use alloca() when malloc() fails, it is vulnerable to stack-based buffer overflows (similar to CVE-2012-4424).

Those issues have been fixed in Debian 6 Squeeze with eglibc 2.11.3-4+deb6u8. We recommend that you upgrade libc6 and other packages provided by eglibc.

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.
