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-200706-09
(libexif: Buffer overflow)

iDefense Labs have discovered that the exif_data_load_data_entry()
function in libexif/exif-data.c improperly handles integer data while
working with an image with many EXIF components, allowing an integer
overflow possibly leading to a heap-based buffer overflow.

Impact :

An attacker could entice a user of an application making use of a
vulnerable version of libexif to load a specially crafted image file,
possibly resulting in a crash of the application or the execution of
arbitrary code with the rights of the user running the application.

Workaround :

There is no known workaround at this time.

Solution :

All libexif users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/libexif-0.6.16'

Risk factor :

Medium / CVSS Base Score : 6.8
