Synopsis

Moderate: librsvg2 security update

Type/Severity

Security Advisory: Moderate

Topic

Updated librsvg2 packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

[Updated Feb 4, 2014]
The original packages distributed with this advisory contained a bug that
caused applications using librsvg2 to crash when loading certain SVG
images. We have updated the packages to correct this bug.

Description

The librsvg2 packages provide an SVG (Scalable Vector Graphics) library
based on libart.

An XML External Entity expansion flaw was found in the way librsvg2
processed SVG files. If a user were to open a malicious SVG file, a remote
attacker could possibly obtain a copy of the local resources that the user
had access to. (CVE-2013-1881)

All librsvg2 users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. All running applications
that use librsvg2 must be restarted for this update to take effect.

Before applying this update, make sure all previously released errata
