Description of changes:

Following Security bug are fixed in this errata

CVE-2010-3904
When copying data to userspace, the RDS protocol failed to verify that
the user-provided address was a valid
userspace address. A local unprivileged user could issue specially
crafted socket calls to write arbitrary
values into kernel memory and potentially escalate privileges to root.

CVE-2010-3067
Integer overflow in the do_io_submit function in fs/aio.c in the Linux
kernel before 2.6.36-rc4-next-20100915
allows local users to cause a denial of service or possibly have
unspecified other impact via crafted use of
the io_submit system call.

CVE-2010-3477
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.
