Multiple Buffer and Integer Overflow Vulnerabilities in Python (python(1)) May Lead to a Denial of Service (DoS) or Allow Execution of Arbitrary Code

1. 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:


2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform
  • Solaris 10 without patch 143506-01
  • OpenSolaris based upon builds snv_01 through snv_120
x86 Platform
  • Solaris 10  without patch 143507-01
  • 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
  • Solaris 10 with patch 143506-01 or later
  • OpenSolaris based upon builds snv_121 or later
x86 Platform
  • Solaris 10 with patch 143507-01 or later
  • OpenSolaris based upon builds snv_121 or later
