-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : windowmaker SUMMARY : Integer buffer overflow vulnerability DATE : 2002-11-18 12:10:00 ID : CLA-2002:548 RELEVANT RELEASES : 6.0, 7.0, 8 - ------------------------------------------------------------------------- DESCRIPTION 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 It is recommended that all Window Maker users upgrade their packages. IMPORTANT: if Window Maker is in use during the update, it will have to be restarted manually. This can be done via the "Exit -> Restart" menu.
