"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.

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."
