Description Jan Lieskovsky 2009-09-16 15:00:24 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2009-2813 to
the following vulnerability:

The SMB (aka Samba) subsystem in Apple Mac OS X 10.5.8, when Windows
File Sharing is enabled, does not properly handle errors in resolving
pathnames, which allows remote authenticated users to bypass intended
sharing restrictions, and read, create, or modify files, in certain
circumstances involving user accounts that lack home directories.
