Impact Multiple buffer and integer overflow vulnerabilities in Python (see python(1)) may allow a local or remote unprivileged user to execute arbitrary code with the privileges of the Python application or crash a Python application resulting in a Denial of Service (DoS). These issues are also referenced in the following documents: CVE-2007-4965 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4965 CVE-2008-1679 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1679 CVE-2008-1721 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1721 CVE-2008-2315 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2315 2. Contributing Factors These issues can occur in the following releases: SPARC Platform * Solaris 10 * OpenSolaris based upon builds snv_01 through snv_120 x86 Platform * Solaris 10 * OpenSolaris based upon builds snv_01 through snv_120 Note: Solaris 8 and Solaris 9 do not ship Python and therefore are not affected by these issues. 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 If one of these issues should occur, a Python application may crash and potentially create a core dump depending on the system configuration. There are no predictable symptoms that would indicate one of these issues has been exploited to execute arbitrary code. 4. Workaround There is no workaround for these issues. Please see the Resolution section below. 5. Resolution These issues are addressed in the following releases: SPARC Platform * OpenSolaris based upon builds snv_121 or later x86 Platform * OpenSolaris based upon builds snv_121 or later A final resolution is pending completion for Solaris 10.
