Security vulnerability in the GNU tar utility (see gtar(1)):

1. Impact

A security vulnerability in the GNU tar utility (see gtar(1)) bundled with Solaris 9 and Solaris 10 may allow a local or remote unprivileged user who provides a specially crafted tar archive to cause the execution of arbitrary code or a program crash. The ability to cause a program crash  is a type of Denial of Service (DoS).

Additional information regarding this issue is available at:

• CVE-2006-0300 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0300
  

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform

• Solaris 9 with patch 118191-01 and without patch 118191-02
  
• Solaris 10 without patch 139099-01
• OpenSolaris based upon builds snv_01 through snv_80

x86 Platform

• Solaris 9 with patch 118192-01 and without patch 118192-02
  
• Solaris 10 without patch 139100-01
• OpenSolaris based upon builds snv_01 through snv_80

Note 1: Solaris 8 does not include support for GNU tar utility and is not impacted by this issue.

Note 2:  OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived.

To determine the base build of  OpenSolaris, the following command can be used:

    $ uname -v
    snv_86

3. Symptoms

There are no predictable symptoms that would indicate the described issue has been exploited on a system.

4. Workaround

Until the patches for this issue can be applied, users should avoid using gtar(1) with archives from untrusted sources.

5. Resolution

This issue is addressed in the following releases:

SPARC Platform

• Solaris 9 with patch 118191-02 or later
• Solaris 10 with patch 139099-01 or later
• OpenSolaris based upon build snv_81 or later

x86 Platform
