CVE-2016-5118

The OpenBlob function in blob.c in GraphicsMagick before 1.3.24 and ImageMagick allows remote attackers to execute arbitrary code via a | (pipe) character at the start of a filename.

The OpenBlob function in blob.c in GraphicsMagick before 1.3.24 and ImageMagick allows remote attackers to execute arbitrary code via a | (pipe) character at the start of a filename.

• A read out-of-bound in the parsing of gif files using GraphicsMagick (CVE-2015-8808).

• Infinite loop caused by converting a circularly defined svg file (CVE-2016-5240).

• Fix another case of CVE-2016-2317 (heap buffer overflow) in the MVG rendering code (also impacts SVG).

• arithmetic exception converting a svg file (CVE-2016-5241)

• Arithmetic exception converting a svg file caused by a X%0 operation in magick/render.c (CVE-2016-2318)

• A shell exploit (CVE-2016-5118) was discovered associated with a filename syntax where file names starting with '|' are intepreted as shell commands executed via popen(). Insufficient sanitization in the SVG and MVG renderers allows such filenames to be passed through from potentially untrusted files. There might be other ways for untrusted inputs to produce such filenames. Due to this issue, support for the feature is removed entirely.

The gnudl, octave, pdf2djvu, and photoqt packages have been rebuilt to use the updated GraphicsMagick++ library.

Updated imagemagick package fixes security vulnerabilities:

The OpenBlob function in blob.c in ImageMagick allows remote attackers to execute arbitrary code via a | (pipe) character at the start of a filename (CVE-2016-5118).

Integer overflow in MagickCore/profile.c (CVE-2016-5841).

Buffer overread in MagickCore/property.c (CVE-2016-5842).

Also, several packages have been rebuilt to use the updated Magick++-6.Q16 library. These include converseen, cuneiform-linux, inkscape, k3d, kcm-grub2, kxstitch, performous, perl-Image-SubImageFind, pfstools, pstoedit, pythonmagick, synfig, vdr-plugin-skinelchi, and vdr-plugin-skinenigmang.

These are all security issues fixed in the ImageMagick-6.9.6.6-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the GraphicsMagick-1.3.25-1.1 package on the GA media of openSUSE Tumbleweed.

This update for ImageMagick fixes the following issues:

This security issue was fixed:

• CVE-2016-5118: Prevent code execution via popen() (bsc#982178)

This non-security issue was fixed:

• Fix encoding of /Title in generated PDFs. (bsc#867943)

This update for ImageMagick fixes the following issues:

• CVE-2016-5118: popen() shell vulnerability via filenames (bsc#982178)

This update for GraphicsMagick fixes the following issues:

• CVE-2016-5118: popen() shell vulnerability via special filenames (bnc#982178).
• CVE-2013-4589: The ExportAlphaQuantumType function in export.c in GraphicsMagick might have allowed remote attackers to cause a denial of service (crash) via vectors related to exporting the alpha of an 8-bit RGBA image (bsc#851064).
• CVE-2015-8808: Out-of-bound read in the parsing of GIF files (bnc#965574).

Nikolay Ermishkin and Stewie discovered that ImageMagick incorrectly sanitized untrusted input. A remote attacker could use these issues to execute arbitrary code. These issues are known as "ImageTragick". This update disables problematic coders via the /etc/ImageMagick-6/policy.xml configuration file. In certain environments the coders may need to be manually re-enabled after making sure that ImageMagick does not process untrusted input. (CVE-2016-3714, CVE-2016-3715, CVE-2016-3716, CVE-2016-3717, CVE-2016-3718)

Bob Friesenhahn discovered that ImageMagick allowed injecting commands via an image file or filename. A remote attacker could use this issue to execute arbitrary code. (CVE-2016-5118)
