CVE-2017-15277: Graphicsmagick

Medium severity, CVSS 6.5. EPSS: 19.2% chance of exploitation in the next 30 days.

ReadGIFImage in coders/gif.c in ImageMagick 7.0.6-1 and GraphicsMagick 1.3.26 leaves the palette uninitialized when processing a GIF file that has neither a global nor local palette. If the affected product is used as a library loaded into a process that operates on interesting data, this data sometimes can be leaked via the uninitialized palette.

Affected products

• Graphicsmagick Graphicsmagick: version 1.3.26 only
• ImageMagick ImageMagick: version 7.0.6-1 only
