USN-359-1: Python vulnerability

06 October 2006

Python vulnerability



Benjamin C. Wiley Sittler discovered that Python's repr() function did
not properly handle UTF-32/UCS-4 strings. If an application uses
repr() on arbitrary untrusted data, this could be exploited to execute
arbitrary code with the privileges of the python application.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 6.06
  • python2.3-dbg - 2.3.5-9ubuntu1.2
  • python2.4-minimal - 2.4.3-0ubuntu6
Ubuntu 5.10
  • python2.3 - 2.3.5-8ubuntu0.2
  • python2.4-minimal - 2.4.2-1ubuntu0.2
Ubuntu 5.04
  • python2.3 - 2.3.5-2ubuntu0.3
  • python2.4-minimal - 2.4.1-0ubuntu0.2

In general, a standard system upgrade is sufficient to effect the
necessary changes.
