correctly check certain lengths. If an attacker sent a truncated
HMAC, it could bypass authentication, leading to potential privilege
escalation. (CVE-2009-0217)

Sebastian Apelt and Frank Reißner discovered that OpenOffice did not
correctly import XPM and GIF images. If a user were tricked into opening
