CVE-2016-10068

The MSL interpreter in ImageMagick before 6.9.6-4 allows remote attackers to cause a denial of service (segmentation fault and application crash) via a crafted XML file.

The imagemagick package has been updated to version 6.9.9.41 which fixes several unspecified security vulnerabilities. This update fixes several vulnerabilities in imagemagick, including: Various memory handling problems and cases of missing or incomplete input sanitising may result in denial of service, memory disclosure or the execution of arbitrary code if malformed GIF, TTF, SVG, TIFF, PCX, JPG or SFW files are processed.

Several packages have been rebuilt for the updated ImageMagick.

This update for GraphicsMagick fixes several issues.

These security issues were fixed:

• CVE-2016-10048: Arbitrary module could have been load because relative path were not escaped (bsc#1017310).
• CVE-2016-10049: Corrupt RLE files could have overflowed a buffer due to a incorrect length calculation (bsc#1017311).
• CVE-2016-10050: Corrupt RLE files could have overflowed a heap buffer due to a missing offset check (bsc#1017312).
• CVE-2016-10051: Fixed use after free when reading PWP files (bsc#1017313).
• CVE-2016-10059: Unchecked calculation when reading TIFF files could have lead to a buffer overflow (bsc#1017318).
• CVE-2016-10064: Improved checks for buffer overflow when reading TIFF files (bsc#1017321).
• CVE-2016-10065: Unchecked calculations when reading VIFF files could have lead to out of bound reads (bsc#1017322).
• CVE-2016-10068: Prevent NULL pointer access when using the MSL interpreter (bsc#1017324).
• CVE-2016-10070: Prevent allocating the wrong amount of memory when reading mat files (bsc#1017326).
• CVE-2016-10146: Captions and labels were handled incorrectly, causing a memory leak that could have lead to DoS (bsc#1020443).
• CVE-2017-5511: A missing cast when reading PSD files could have caused memory corruption by a heap overflow (bsc#1020448).

• CVE-2017-5510: Prevent out-of-bounds write when reading PSD files (bsc#1020446).
• CVE-2017-5511: A missing cast when reading PSD files could have caused memory corruption by a heap overflow (bsc#1020448)

This update removes the fix for CVE-2016-9773. ImageMagick-6 was not affected by CVE-2016-9773 and it caused a regression (at least in GraphicsMagick) (bsc#1017421).
