Synopsis:	Moderate: kernel security and bug fix update

Issue date:	2011-03-01

CVE Names:	CVE-2010-4249 CVE-2010-4251 CVE-2010-4655



This update fixes the following security issues:



* A flaw was found in the Linux kernel's garbage collector for AF_UNIX

sockets. A local, unprivileged user could use this flaw to trigger a

denial of service (out-of-memory condition). (CVE-2010-4249, Moderate)



* A flaw was found in the Linux kernel's networking subsystem. If the

number of packets received exceeded the receiver's buffer limit, they 

were queued in a backlog, consuming memory, instead of being discarded. 

A remote attacker could abuse this flaw to cause a denial of service 

(out-of-memory condition). (CVE-2010-4251, Moderate)



* A missing initialization flaw was found in the ethtool_get_regs()

function in the Linux kernel's ethtool IOCTL handler. A local user who 

has the CAP_NET_ADMIN capability could use this flaw to cause an 

information leak. (CVE-2010-4655, Low)



This update also fixes several bugs.



The system must be rebooted for this update to take effect.



NOTE: For those who have tested our updated openafs package for SL5, you 

will need to enable the sl-testing repository to properly do this 

update.  We apologize for this.

   yum --enablerepo=sl-testing update kernel\*

Again, this is only for those who have updated openafs to 1.4.14



SL 5.x
