Buffer overflow in the getaddrinfo function in Python 2.2 before 2.2.2, when IPv6 support is disabled, allows remote attackers to execute arbitrary code via an IPv6 address that is obtained using DNS.

This security advisory corrects DSA 458-2 which caused a problem in the gethostbyaddr routine.

The original advisory said:

> Sebastian Schmidt discovered a buffer overflow bug in Python's getaddrinfo function, which could allow an IPv6 address, supplied by a remote attacker via DNS, to overwrite memory on the stack.
> 
> This bug only exists in python 2.2 and 2.2.1, and only when IPv6 support is disabled. The python2.2 package in Debian woody meets these conditions (the 'python' package does not).

For the stable distribution (woody), this bug has been fixed in version 2.2.1-4.6.

The testing and unstable distribution (sarge and sid) are not affected by this problem.

We recommend that you update your python2.2 packages.

CVE-2004-0150: Debian -- Security Information -- DSA-458-3 python2.2

os._execvpe from os.py in Python 2.2.1 and earlier creates temporary files with predictable names, which could allow local users to execute arbitrary code via a symlink attack.

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 1.5.2-23.1 of Python 1.5, in version 2.1.3-3.1 of Python 2.1 and in version 2.2.1-4.1 of Python 2.2. For the old stable distribution (potato) this has been fixed in version 1.5.2-10potato12 for Python 1.5. For the unstable distribution (sid) this has been fixed in version 1.5.2-24 of Python 1.5, in version 2.1.3-6a of Python 2.1 and in version 2.2.1-8 of Python 2.2. Python 2.3 is not affected by this problem.

We recommend that you upgrade your Python packages immediately.
