Debian DLA-500-1 : imagemagick security update
Critical Nessus Plugin ID 91444
SynopsisThe remote Debian host is missing a security update.
DescriptionBob Friesenhahn from the GraphicsMagick project discovered a command injection vulnerability in ImageMagick, a program suite for image manipulation. An attacker with control on input image or the input filename can execute arbitrary commands with the privileges of the user running the application.
This update removes the possibility of using pipe (|) in filenames to interact with imagemagick.
It is important that you upgrade the libmagickcore5 and not just the imagemagick package. Applications using libmagickcore5 might also be affected and need to be restarted after the upgrade.
For Debian 7 'Wheezy', these problems have been fixed in version 8:126.96.36.199-5+deb7u6.
We recommend that you upgrade your imagemagick packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected packages.
