Multiple Security Vulnerabilities Within the GIMP Plugins

Category :	Security
Release Phase :	Resolved
Product :	Solaris 10 Operating System
Bug Id :	6569992, 6569966, 6263045
Date of Workaround Release :	17-Dec-2007
Date of Resolved Release :	10-Sep-2008

Multiple security vulnerabilities exist within the plugins used by the Gnome Image manipulation and paint program (gimp(1)):

Impact

Multiple security vulnerabilities exist within the plugins used by the Gnome Image manipulation and paint program (gimp(1)).

These security vulnerabilities which are within the sunras, psd, and pcx plugins of (gimp(1)), may allow a remote unprivileged user the ability to crash (gimp(1)) and execute arbitrary code with the privileges of a local user when (gimp(1)) loads a carefully crafted Sun Raster image file, PSD image file, or PCX image file.

These issues are described in the following documents:

CVE-2007-2356 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2356
CVE-2007-2949 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2949
CVE-2005-1046 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1046

Contributing Factors

These issues can occur in the following releases:

SPARC Platform

Solaris 10 without patch 122212-22

x86 Platform

Solaris 9 with JDS release 2 installed without patch 121775-01
Solaris 10 without patch 122213-22

Note: Solaris 8 and Solaris 9 on the SPARC platform and Solaris 8 on the x86 platform are not affected by this issue.

To determine the version of GNOME that is currently installed on the system, the following command can be run (output will vary by platform):

    % grep distributor /usr/share/gnome/gnome-about/gnome-version.xml
    <distributor-version>Sun Java Desktop System, Release 2</distributor-version>

Alternatively (for the same results), in a terminal window from within the GNOME desktop, the following command can be run:

    % /usr/bin/gnome-about

Symptoms

If the described issues occur, (gimp(1)) will crash without warning when loading one of the affected file formats.

Workaround

To work around the described issues, only load images from trusted sources.

At least one of the documented issues can be worked around by using the "noexec_user_stack" options to defeat the most common form of buffer overflow attacks that store executable exploit code on the stack. This can be achieved by editing the "/etc/system" file and adding the lines:

    set noexec_user_stack = 1
    set noexec_user_stack_log = 1

Note: A reboot will be necessary in order for the "/etc/system" change to take effect.

Resolution

These issues are addressed in the following releases:

SPARC Platform

Solaris 10 with patch 122212-22 or later

x86 Platform

Solaris 9 with JDS release 2 with patch 121775-01 or later
Solaris 10 with patch 122213-22 or later
