USN-304-1: gnupg vulnerability

Publication date

27 June 2006

Overview

gnupg vulnerability

Releases

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.
