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
