Description

(Note CVE-2016-4347 is a duplicate of CVE-2015-7558)

Two DoS in librsvg 2.40.2 parsing SVGs with circular definitions were found (they will produce stack exhaustion) by Gustavo Grieco.

The version in wheezy (2.36.1-2+deb7u1) is also vulnerable.

For Debian 7 'Wheezy', these problems have been fixed in version 2.36.1-2+deb7u2.

We recommend that you upgrade your librsvg packages.

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.
