Description Nick Barkas 2008-04-28 01:10:00 UTC
Python 2.3 and 2.4 suffer from the same integer signedness bug in the zlib module as was fixed recently in the port python25-2.5.2_2. See http://www.vuxml.org/freebsd/ec41c3e2-129c-11dd-bab7-0016179b2dd5.html

Fix: 

Add the patch currently in lang/python25/files/patch-Modules-zlibmodule.c to lang/python24/files and lang/python23/files. It would also be good to update security/vuxml/vuln.xml to note that the vulnerability also affects python23 and python24 packages with version and port revision numbers before this patch is added.
How-To-Repeat: Run either of the scipts python-2.5.2-zlib-unflush-misallocation.py or python-2.5.2-zlib-unflush-signedness.py attached to the bug reported at http://bugs.python.org/issue2586. Unpatched python 2.3 or 2.4 will crash, just as unpatched python 2.5 will.
