RHBA-2012:0297 - Bug Fix Advisory

Topic

Updated python packages that fix multiple bugs are now available for Red Hat
Enterprise Linux 5.

Description

Python is an interpreted, interactive, object-oriented programming language.
Python includes modules, classes, exceptions, high-level dynamic data types and
dynamic typing. Python supports interfaces to many system calls and libraries,
as well as to various windowing systems (X11, Motif, Tk, Mac and MFC).

This update fixes the following bugs:

• The urllib.unquote method uses a dictionary containing pairs of hexadecimal

values. Prior to this update, this dictionary only contained those combinations
where the hexadecimal digits were both upper case or lower case, omitting those
pairs where one digit was upper case, the other lower case. As a result,
percent-escape sequences containing both upper and lower case hexadecimal
characters were not decoded in Python. This update modifies the dictionary
creation code so that it includes keys for all combinations of upper and lower
case hexadecimal digits. Now, all mixed-case hexadecimal digit pairs are
correctly decoded by the urllib.unquote method. (BZ#732954)

• Prior to this update, python did not include an alias for "en_in" to convert

"en_IN" into "en_IN.ISO8859-1". Consequently, the yum grouplist command would
not work when the console LANG variable was set as follows: LANG=en_IN. With
this update, an alias has been added in the locale.py file and yum grouplist now
functions as expected with LANG=en_IN. (BZ#708292)

All Python users are advised to upgrade to these updated packages, which fix
these bugs.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
