net/sched/act_police.c infoleak
CVE: CVE-2010-3477
Component: kernel
Severity: Moderate
Release date: 2010-09-01T00:00:00+00:00

The tcf_act_police_dump function in net/sched/act_police.c in the actions implementation in the network queueing functionality in the Linux kernel before 2.6.36-rc4 does not properly initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel memory via vectors involving a dump operation.  NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-2942.

To install kernel packages manually, use "rpm -ivh [package]". Do not
use "rpm -Uvh" as that will remove the running kernel binaries from
your system. You may use "rpm -e" to remove old kernels after
determining that the new kernel functions properly on your system.
