SA Document Body

Multiple Security Vulnerabilities in Solaris Ghostscript (GS(1)) May lead 
to Denial of Service (DoS) or Execution of Arbitrary Code

1. Impact

Multiple security vulnerabilities exist in Ghostscript(GS(1)), an 
interpreter for the PostScript and PDF language. Ghostscript is bundled in 
Solaris 9 and 10.

These issues may allow local or remote unprivileged users to supply 
specially crafted PostScript or PDF files, thereby causing a Denial of 
Service (DoS) condition to applications using the Ghostscript interpreter, 
or lead to execution of arbitrary code with the privileges of the user 
running Ghostscript.

Additional information regarding these issues is available at:

CVE-2007-6725 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6725
CVE-2008-6679 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-6679
CVE-2009-0196 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0196
CVE-2009-0583 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0583
CVE-2009-0584 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0584
CVE-2009-0792 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0792

2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform

    * Solaris 9
    * Solaris 10 without patch 122259-02
    * OpenSolaris based upon builds snv_01 through snv_114

x86 Platform

    * Solaris 9
    * Solaris 10 without patch 122260-02
    * OpenSolaris based upon builds snv_01 through snv_114

Note: Solaris 8 does not include support for Ghostscript and therefore is 
      not impacted by these issues.

OpenSolaris distributions may include additional bug fixes above and beyond 
the build from which it was derived. The base build can be derived as 

$ uname -v

3. Symptoms

There are no predictable symptoms that would indicate these issues have 
been exploited.

4. Workaround

Until patches are available, users should avoid processing PostScript and
PDF files from untrusted sources.

5. Resolution

These issues are addressed in the following releases:

SPARC Platform

    * Solaris 9 with patch 115835-04 or later
    * Solaris 10 with patch 122259-02 or later
    * OpenSolaris based upon builds snv_115 or later

x86 Platform

    * Solaris 9 with patch 115836-04 or later
    * Solaris 10 with patch 122260-02 or later
    * OpenSolaris based upon builds snv_115 or later

A final resolution is pending completion for Solaris 9.
