Description

The XML::LibXML perl module is affected by a 'use-after-free' vulnerability which allows remote attackers to execute arbitrary code by controlling the arguments to a replaceChild() call.

For Debian 7 'Wheezy', these problems have been fixed in version 2.0001+dfsg-1+deb7u2.

We recommend that you upgrade your libxml-libxml-perl 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.
