2. Free Market Filtering
By Mark Rasch
The Australian government is considering requiring that Internet service providers in that country install filters which would prevent citizens from accessing tens of thousands of sites that contain "objectionable" material.

Summary:
Linux-PAM is prone to a vulnerability related to the parsing of user names containing non-ASCII characters from PAM configuration files. Specifically, this issue is caused by an error in the '_pam_StrTok()' function, which may strip a single trailing non-ASCII character from user names before returning them as 'arg3'.

Note that root access is required to modify the affected configuration files.

A local attacker may exploit this issue to authenticate as additional users. The attacker may be able to create a denial-of-service condition or possibly to execute arbitrary code as the affected process, but this has not been confirmed.

Versions prior to Linux-PAM 1.0.4 are vulnerable.
