Synopsis
Vulnerabilities found in ImageMagick might allow remote attackers
to execute arbitrary code.
2.
Impact Information
Background
ImageMagick is a collection of tools and libraries for manipulating
various image formats.
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.
3.
Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All ImageMagick users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.7.5.3"
|
