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 with Solaris 9 and Solaris 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:


2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform

• Solaris 9 without patch 115835-04
• Solaris 10 without patch 122259-02
• OpenSolaris based upon builds snv_01 through snv_114

x86 Platform

• Solaris 9 without patch 115836-04
• 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 follows:

$ uname -v
snv_86

3. Symptoms

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

4. Workaround

Until patches can be installed, 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
