Title

OpenBSD Security Bulletin:

Security Vulnerability in Xpm Library.

Detail
====== 

Chris Evans reported several flaws (stack and integer overflows) in the Xpm library 
code that parses image files.


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


Chris Evans reported several flaws (stack and integer overflows) in the Xpm library 
code that parses image files (CAN-2004-0687, CAN-2004-0688). Some of these would be 
exploitable when parsing malicious image files in an application that handles XPM 
images, if they could escape ProPolice.

The fixes have been committed to OpenBSD -current as well as the 3.4 and 3.5 -stable 
branches.

Patches against OpenBSD 3.4 and 3.5 are also available:
    ftp://ftp.OpenBSD.org/pub/OpenBSD/patches/3.4/common/030_xpm.patch
    ftp://ftp.OpenBSD.org/pub/OpenBSD/patches/3.5/common/019_xpm.patch
