Package : python Vulnerability : insecure temporary files Problem-Type : local Debian-specific: no BugTraq ID : 5581
[The mail just sent was formatted like an attachment due to a misconception on my side. This mail is only the clearsign version. ]
The bugfix we distributed in DSA 159-1 unfortunately caused Python to sometimes behave improperly when a non-executable file existed earlier in the path and an executable file of the same name existed later in the path. Zack Weinberg fixed this in the Python source. For reference, here's the original advisory text:
Zack Weinberg discovered an insecure use of a temporary file in os._execvpe from os.py. It uses a predictable name which could lead execution of arbitrary code.
This problem has been fixed in several versions of Python: For the current stable distribution (woody) it has been fixed in version 1.5.2-23.2 of Python 1.5, in version 2.1.3-3.2 of Python 2.1 and in version 2.2.1-4.2 of Python 2.2. For the old stable distribution (potato) this has been fixed in version 1.5.2-10potato13 for Python 1.5. For the unstable distribution (sid) this has been fixed in version 1.5.2-25 of Python 1.5, in version 2.1.3-9 of Python 2.1 and in version 2.2.1-11 of Python 2.2. Python 2.3 is not affected by the original problem.
We recommend that you upgrade your Python packages.
wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
If you are using the apt-get package manager, use the line for sources.list as given below:
apt-get update will update the internal database apt-get upgrade will install corrected packages
