[issue5753] CVE-2008-5983 python: untrusted python modules search path

[Jan Lieskovsky]

New submission from Jan Lieskovsky <iankko at seznam.cz>:

Common Vulnerabilities and Exposures assigned an identifier
CVE-2008-5983 (and related CVE ids) to the following vulnerability:

Untrusted search path vulnerability in the PySys_SetArgv API function in
Python 2.6 and earlier, and possibly later versions, prepends an empty
string to sys.path when the argv[0] argument does not contain a path
separator, which might allow local users to execute arbitrary code via a
Trojan horse Python file in the current working directory.
