Description Eugene Teo (Security Response) 2008-07-21 04:47:34 EDT
Description of problem:
Given an illegal selinux option it was possible for match_token to work in
random memory at the end of the match_table_t array.

Note that privilege is required to perform a context mount, so this issue is
effectively limited to root only.
