"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.

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."
