Synopsis ========
An integer overflow in ImageMagick might allow remote attackers to cause the remote execution of 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 < 6.5.2.9 >= 6.5.2.9
Description ===========
Tielei Wang has discovered that the XMakeImage() function in magick/xwindow.c is prone to an integer overflow, possibly leading to a buffer overflow.
Impact ======
A remote attacker could entice a user to open a specially crafted image, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All ImageMagick users should upgrade to an unaffected version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.5.2.9"
NOTE: This is a legacy GLSA. Updates for all affected architectures are available since June 4, 2009. It is likely that your system is already no longer affected by this issue.
