Scientific Linux Security Update : python on SL4.x i386/x86_64
High Nessus Plugin ID 60960
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionMultiple 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. (CVE-2009-4134, CVE-2010-1449, CVE-2010-1450)
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. (BZ#436001)
- Python 2.3.4's socket.htons() function returned partially-uninitialized data on IBM System z, generally leading to incorrect results. (BZ#513341)
- 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. (BZ#497540)
SolutionUpdate the affected packages.
