Pardus Linux Security Advisory 2008-31 security@pardus.org.tr
Date: 2008-08-27 Severity: 3 Type: Remote ------------------------------------------------------------------------


A vulnerability has been reported in LibTIFF, which can be exploited by malicious people to cause a DoS (Denial of Service) or to potentially compromise a user's system.


The vulnerability is caused due to errors within the "LZWDecode()" and "LZWDecodeCompat()" functions in libtiff/tif_lzw.c. These can be exploited to cause a buffer underflow via a specially crafted TIFF file.

Affected packages:

   Pardus 2008:
     tiff, all before 3.8.2-9-3
   Pardus 2007:
     tiff, all before 3.8.2-8-7


There are update(s) for tiff. You can update them via Package Manager or with a single command from console:

   Pardus 2008:
     pisi up tiff

   Pardus 2007:
     pisi up tiff
