Mandriva Linux Security Advisory : imagemagick (MDVSA-2012:078)
high Nessus Plugin ID 61952
Language:
Synopsis
The remote Mandriva Linux host is missing one or more security updates.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.
