Date Reported:
04 Feb 2005
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2005-0089.
More information:

The Python development team has discovered a flaw in their language package. The SimpleXMLRPCServer library module could permit remote attackers unintended access to internals of the registered object or its module or possibly other modules. The flaw only affects Python XML-RPC servers that use the register_instance() method to register an object without a _dispatch() method. Servers using only register_function() are not affected.

For the stable distribution (woody) this problem has been fixed in version 2.2.1-4.7. No other version of Python in woody is affected.

For the testing (sarge) and unstable (sid) distributions the following matrix explains which version will contain the correction in which version:

  testing unstable
Python 2.2 2.2.3-14 2.2.3-14
Python 2.3 2.3.4-20 2.3.4+2.3.5c1-2
Python 2.4 2.4-5 2.4-5

We recommend that you upgrade your Python packages.

Fixed in:

Debian GNU/Linux 3.0 (woody)
