CVE-2016-10048

Directory traversal vulnerability in magick/module.c in ImageMagick 6.9.4-7 allows remote attackers to load arbitrary modules via unspecified vectors.

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-2017-5511: 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).
