GLSA-200602-06 : ImageMagick: Format string vulnerability
Medium Nessus Plugin ID 20896
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200602-06 (ImageMagick: Format string vulnerability)
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. This is a new vulnerability that is not addressed by GLSA 200503-11.
By feeding specially crafted file names to ImageMagick, an attacker can crash the program and possibly execute arbitrary code with the privileges of the user running ImageMagick.
There is no known workaround at this time.
SolutionAll ImageMagick users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-gfx/imagemagick-22.214.171.124'
