 Mandriva Linux Security Advisory                         MDVSA-2012:174
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : libtiff
 Date    : November 22, 2012
 Affected: 2011., Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities was found and corrected in libtiff:
 
 Heap-based buffer overflow in tif_pixarlog.c in LibTIFF before 4.0.3
 allows remote attackers to cause a denial of service (application
 crash) and possibly execute arbitrary code via a crafted TIFF image
 using the PixarLog Compression format (CVE-2012-4447).
 
 ppm2tiff does not check the return value of the TIFFScanlineSize
 function, which allows remote attackers to cause a denial of service
 (crash) and possibly execute arbitrary code via a crafted PPM image
 that triggers an integer overflow, a zero-memory allocation, and a
 heap-based buffer overflow (CVE-2012-4564).
 
 The updated packages have been patched to correct these issues.
