Python is an interpreted, interactive, object-oriented programming language. Multiple flaws were found in the Python rgbimg module. If an application written in Python was using the rgbimg module and loaded a specially-crafted SGI image file, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. This update also fixes the following bugs: * Python 2.3.4"s time.strptime function did not correctly handle the "%W" week number format string. This update backports the _strptime implementation from Python 2.3.6, fixing this issue. * Python 2.3.4"s socket.htons function returned partially-uninitialized data on IBM System z, generally leading to incorrect results. * Python 2.3.4"s pwd.getpwuid and grp.getgrgid functions did not support the full range of user and group IDs on 64-bit architectures, leading to "OverflowError" exceptions for large input values. This update adds support for the full range of user and group IDs on 64-bit architectures. Users of Python should upgrade to these updated packages, which contain backported patches to correct these issues.
