Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several heap-based buffer overflows, integer overflows and NULL pointer dereferences have been discovered in libpodofo, a library for manipulating PDF files, that allow remote attackers to cause a denial of service (application crash) or other unspecified impact via a crafted PDF document.

For Debian 7 'Wheezy', these problems have been fixed in version 0.9.0-1.1+deb7u1.

We recommend that you upgrade your libpodofo packages.
