CONECTIVA LINUX SECURITY ANNOUNCEMENT
- --------------------------------------------------------------------------

PACKAGE : windowmaker
SUMMARY : Remote buffer overflow
DATE : 2001-08-13 18:11:00
ID : CLA-2001:411
RELEVANT
RELEASES : 4.0, 4.0es, 4.1, 4.2, 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0

- -------------------------------------------------------------------------

DESCRIPTION
Window Maker is a popular window manager.
Robert Marshall reported a crash problem with Window Maker. Further
investigation by Alban Hertroys showed this to be a buffer overflow
in the window title handling code.
Many applications, in particular web browsers, set the window title
to something obtained from the network, such as the title of a
webpage being viewed by an user. Thus this could be exploited
remotely.
The authors of Window Maker, with contributions from Alban Hertroys,
released a new version (0.65.1) which addresses this vulnerability. A
patch was made available for previous versions.

SOLUTION
It is recommended that all Window Maker users upgrade their packages.
Versions below 0.65.1 have been patched to correct this
vulnerability.

IMPORTANT: after applying the update, Window Maker has to be
restarted if it was running during the upgrade. To do this, select
"Restart" from the "Exit" menu.
