Test ID:1.3.6.1.4.1.25623.1.0.51555
Category:Conectiva Local Security Checks
Title:Conectiva Security Advisory CLA-2002:548
Summary:Conectiva Security Advisory CLA-2002:548
Description:
The remote host is missing updates announced in
advisory CLA-2002:548.

Window Maker[1] is a very popular window manager.

Al Viro reported a vulnerability[2] in a function that is used when
Window Maker loads images. This function is used, for example, when a
new background image is configured, and when previewing themes.

This function calculates the ammount of memory necessary to load the
image by doing a multiplication. It does not, however, check the
result of this multiplication, which could suffer an integer overflow
and not fit into the destination variable. Given a sufficiently large
height and/or width parameter, a less than needed ammount of memory
would be allocated, which would result in a buffer overflow later on
when the image is actually loaded.

A possible scenario for this vulnerability could be that of an
attacker making a specially crafted image available and convincing an
unsuspecting user to set it as a background image.


Solution:
The apt tool can be used to perform RPM package upgrades
by running 'apt-get update' followed by 'apt-get upgrade'
