Systems running Ubuntu 10.10 Maverick can now use Ksplice to patch against

# uptrack-upgrade -y


* CVE-2010-3477: Kernel information leak in act_police.

Incorrectly initialized structures in the traffic control dump code may 
allow the disclosure of kernel memory to userspace applications. This is a 
similar issue to CVE-2010-2942.

* CVE-2010-3904: Local privilege escalation vulnerability in RDS sockets.

The rds_page_copy_user function did not perform any access checks on 
user-provided pointers before using unchecked __copy_*_user_inatomic 
functions, which can be exploited by a local user to write to arbitrary 
kernel memory and escalate privileges.


Ksplice support is available at support at ksplice.com or +1 765-577-5423.
