Description

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.
