dvipng vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
- Ubuntu 9.10
- Ubuntu 9.04
Software description

Details
Dan Rosenberg discovered that dvipng incorrectly handled certain malformed
dvi files. If a user or automated system were tricked into processing a
specially crafted dvi file, an attacker could cause a denial of service via
application crash, or possibly execute arbitrary code with the privileges
of the user invoking the program.
