Several heap-based buffer 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+deb7u2.

We recommend that you upgrade your libpodofo packages.
