-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2007.1024 -- [Solaris] Multiple Security Vulnerabilities Within the GIMP Plugins 12 September 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: GIMP Publisher: Sun Microsystems Operating System: Solaris 10 and 9 Impact: Execute Arbitrary Code/Commands Denial of Service Access: Remote/Unauthenticated CVE Names: CVE-2007-2949 CVE-2007-2356 CVE-2005-1046 Ref: ESB-2007.0498 Revision History: September 12 2008: Contributing Factors and Resolution updated December 20 2007: Resolution updated December 19 2007: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- Sun(sm) Alert Notification * Sun Alert ID: 103170 * Synopsis: Multiple Security Vulnerabilities Within the GIMP Plugins * Category: Security * Product: Solaris 10 Operating System * BugIDs: 6569992, 6569966, 6263045 * Avoidance: Patch, Workaround * State: Workaround * Date Released: 17-Dec-2007 * Date Closed: * Date Modified: 18-Nov-2007 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 2. 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-versio n> Alternatively (for the same results), in a terminal window from within the GNOME desktop, the following command can be run: % /usr/bin/gnome-about 3. Symptoms If the described issues occur, (gimp(1)) will crash without warning when loading one of the affected file formats. 4. Relief/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. 5. 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 Change History 18-Nov-2007: * Updated Contributing Factors and Resolution sections.
