GENTOO LINUX SECURITY ANNOUNCEMENT

PACKAGE        :python
SUMMARY        :os.execvpe() vulnerability
DATE           :2002-10-03 14:45 UTC

- - --------------------------------------------------------------------

OVERVIEW

By exploiting this vulnerability a local attacker can execute
arbitrary code with the privileges of the user running python code
which uses the execvpe() method.

DETAIL

Zack Weinberg found a vulnerability in the way the exevpe() method
from the os.py module uses a temporary file name. A file which
supposedly should not exist is created in a unsafe way and the method
tries to execute it. The objective of such code is to discover what
error the operating system returns in a portable way.

SOLUTION

It is recommended that all Gentoo Linux users who are running
dev-lang/python-2.2.1-r4 and earlier update their systems
as follows:

emerge rsync
emerge python
emerge clean
