overflow.


Here are the details from the Slackware 10.2 ChangeLog:
+--------------------------+
patches/packages/gnupg-1.4.5-i486-1_slack10.2.tgz:
 Upgraded to gnupg-1.4.5.
 From the gnupg-1.4.5 NEWS file:
 * Fixed 2 more possible memory allocation attacks. They are
 similar to the problem we fixed with 1.4.4. This bug can easily
 be be exploited for a DoS, remote code execution is not entirely
 impossible.
(* Security fix *)
+--------------------------+");
