Details

Evgeny Legerov discovered that GnuPG did not sufficiently check overly
large user ID packets. Specially crafted user IDs caused a buffer
overflow. By tricking an user or remote automated system into
processing a malicous GnuPG message, an attacker could exploit this to
crash GnuPG or possibly even execute arbitrary code.
