Synopsis ========
A vulnerability in GraphicsMagick allows attackers to crash the application and potentially execute arbitrary code.
Background ==========
GraphicsMagick is a collection of tools to read, write and manipulate images in many formats.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/graphicsmagick < 1.1.7 >= 1.1.7
Description ===========
The SetImageInfo function was found vulnerable to a format string mishandling. Daniel Kobras discovered that the handling of "%"-escaped sequences in filenames passed to the function is inadequate in ImageMagick GLSA 200602-06 and the same vulnerability exists in GraphicsMagick.
Impact ======
By feeding specially crafted file names to GraphicsMagick an attacker can crash the program and possibly execute arbitrary code with the privileges of the user running GraphicsMagick.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All GraphicsMagick users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.7"
References ==========
