Gentoo Linux Security Advisory

Title: ImageMagick: User-assisted execution of arbitrary code (GLSA 201006-03)
Severity: normal
Exploitable: remote
Date: June 01, 2010
Bug(s): #271502
ID: 201006-03

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: media-gfx/imagemagick
Vulnerable: < 6.5.2.9
Unaffected: >= 6.5.2.9
Architectures: All supported architectures


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:
Code:
# 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.
