Debian DLA-563-1 : libgd2 security update

medium Nessus Plugin ID 92570

Language:

Synopsis

The remote Debian host is missing a security update.

Description

A global out of bounds read when encoding gif from malformed input was found in this software.

When given invalid inputs, we might be fed the EOF marker before it is actually the EOF. The gif logic assumes once it sees the EOF marker, there won't be any more data, so it leaves the cur_bits index possibly negative. So when we get more data, we underflow the masks array.

For Debian 7 'Wheezy', these problems have been fixed in version 2.0.36~rc1~dfsg-6.1+deb7u5.

We recommend that you upgrade your libgd2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
