GLSA-200707-04 : GNU C Library: Integer overflow

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200707-04
(GNU C Library: Integer overflow)

Tavis Ormandy of the Gentoo Linux Security Team discovered a flaw in
the handling of the hardware capabilities mask by the dynamic loader.
If a mask is specified with a high population count, an integer
overflow could occur when allocating memory.

Impact :

As the hardware capabilities mask is honored by the dynamic loader
during the execution of suid and sgid programs, in theory this
vulnerability could result in the execution of arbitrary code with root
privileges. This update is provided as a precaution against currently
unknown attack vectors.

Workaround :

There is no known workaround at this time.

Solution :

All users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-libs/glibc-2.5-r4'

Risk factor :

High / CVSS Base Score : 7.2
