Synopsis ========
Vulnerabilities found in ImageMagick might allow remote attackers to execute arbitrary code.
Background ==========
ImageMagick is a collection of tools and libraries for manipulating various image formats.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/imagemagick < 6.7.5.3 >= 6.7.5.3
Description ===========
Two vulnerabilities have been found in ImageMagick:
* Incorrect offset and count values in the ResolutionUnit tag in EXIF IFD could cause memory corruption (CVE-2012-0247). * IOP tag offsets pointing to the beginning of an IFD could cause an infinite loop of ImageMagick parsing the IFD structure (CVE-2012-0248).
Impact ======
A remote attacker could entice a user to open a specially crafted image, possibly resulting in execution of arbitrary code or a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All ImageMagick users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.7.5.3"
