-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : python SUMMARY : os.execvpe() vulnerability DATE : 2002-10-01 11:48:00 ID : CLA-2002:527 RELEVANT RELEASES : 6.0, 7.0, 8 - ------------------------------------------------------------------------- DESCRIPTION Python is an interpreted, interactive, object-oriented programming language. Zack Weinberg found[1] 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. This vulnerability affects all python versions and is fixed[2,3] in the python CVS repository (using a better approach). 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. SOLUTION All python users should upgrade.
