Debian DSA-100-1 : gzip - Potential buffer overflow

high Nessus Plugin ID 14937

Synopsis

The remote Debian host is missing a security-related update.

Description

GOBBLES found a buffer overflow in gzip that occurs when compressing files with really long filenames. Even though GOBBLES claims to have developed an exploit to take advantage of this bug, it has been said by others that this problem is not likely to be exploitable as other security incidents.

Additionally, the Debian version of gzip from the stable release does not segfault, and hence does not directly inherit this problem.
However, better be safe than sorry, so we have prepared an update for you.

Please make sure you are running an up-to-date version from stable/unstable/testing with at least version 1.2.4-33.

Solution

Upgrade the affected gzip package.
