Debian: DSA 608-1 Critical: Zgv Integer Overflows Threat and Fix

Luke Macken and "infamous41md" independently discoverd multiple
integer overflows in zgv. Remote exploitation of an integer
overflow vulnerability could allow the execution of arbitrary
code.

CAN-2004-0999

Mikulas Patocka discovered that malicious multiple-image (e.g.
animated) GIF images can cause a segmentation fault in zgv.

For the stable distribution (woody) these problems have been fixed in
version 5.5-3woody1.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your zgv package immediately.
