 Mandriva Linux Security Advisory                         MDVSA-2012:078
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : imagemagick
 Date    : May 17, 2012
 Affected: 2011.
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been found and corrected in imagemagick:
 
 A flaw was found in the way ImageMagick processed images with malformed
 Exchangeable image file format (Exif) metadata. An attacker could
 create a specially-crafted image file that, when opened by a victim,
 would cause ImageMagick to crash or, potentially, execute arbitrary
 code (CVE-2012-0247).
 
 A denial of service flaw was found in the way ImageMagick processed
 images with malformed Exif metadata. An attacker could create a
 specially-crafted image file that, when opened by a victim, could
 cause ImageMagick to enter an infinite loop (CVE-2012-0248).
 
 The original fix for CVE-2012-0247 failed to check for the possibility
 of an integer overflow when computing the sum of number_bytes and
 offset. This resulted in a wrap around into a value smaller than
 length, making original CVE-2012-0247 introduced length check still
 to be possible to bypass, leading to memory corruption (CVE-2012-1185).
 
 An integer overflow flaw was found in the way ImageMagick processed
 certain Exif tags with a large components count. An attacker
 could create a specially-crafted image file that, when opened by a
 victim, could cause ImageMagick to access invalid memory and crash
 (CVE-2012-0259).
 
 A denial of service flaw was found in the way ImageMagick decoded
 certain JPEG images. A remote attacker could provide a JPEG image with
 specially-crafted sequences of RST0 up to RST7 restart markers (used
 to indicate the input stream to be corrupted), which once processed
 by ImageMagick, would cause it to consume excessive amounts of memory
 and CPU time (CVE-2012-0260).
 
 An out-of-bounds buffer read flaw was found in the way ImageMagick
 processed certain TIFF image files. A remote attacker could provide
 a TIFF image with a specially-crafted Exif IFD value (the set of tags
 for recording Exif-specific attribute information), which once opened
 by ImageMagick, would cause it to crash (CVE-2012-1798).
 
 The updated packages have been patched to correct these issues.
