Package name:           python
Advisory ID:            MDKSA-2002:082
Date:                   November 25th, 2002

Affected versions:      7.2, 8.0, 8.1, 8.2, 9.0,

Problem Description:

 A vulnerability was discovered in python by Zack Weinberg in the way
 that the execvpe() method from the os.py module uses a temporary file
 name.  The file is created in an unsafe manner and execvpe() tries to
 execute it, which can be used by a local attacker to execute arbitrary
 code with the privilege of the user running the python code that is
 using this method.
