Category Security Release Phase Resolved 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:
These issues can occur in the following releases: SPARC Platform
x86 Platform
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 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. WorkaroundTo 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 Note: A reboot will be necessary in order for the "/etc/system" change to take effect. ResolutionThese issues are addressed in the following releases: SPARC Platform
x86 Platform
