Red Hat Security Advisory

 

Synopsis: Important: kernel security and bug fix update

Advisory ID: RHSA-2009:1222-02

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1222.html

Issue date: 2009-08-24

CVE Names: CVE-2009-2692 CVE-2009-2698

=====================================================================

 

1. Summary:

 

Updated kernel packages that fix two security issues and a bug are now

available for Red Hat Enterprise Linux 5.

 

This update has been rated as having important security impact by the Red

Hat Security Response Team.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64

 

3. Description:

 

The kernel packages contain the Linux kernel, the core of any Linux

operating system.

 

These updated packages fix the following security issues:

 

* a flaw was found in the SOCKOPS_WRAP macro in the Linux kernel. This

macro did not initialize the sendpage operation in the proto_ops structure

correctly. A local, unprivileged user could use this flaw to cause a local

denial of service or escalate their privileges. (CVE-2009-2692, Important)

 

* a flaw was found in the udp_sendmsg() implementation in the Linux kernel

when using the MSG_MORE flag on UDP sockets. A local, unprivileged user

could use this flaw to cause a local denial of service or escalate their

privileges. (CVE-2009-2698, Important)

 

Red Hat would like to thank Tavis Ormandy and Julien Tinnes of the Google

Security Team for responsibly reporting these flaws.

 

These updated packages also fix the following bug:

 

* in the dlm code, a socket was allocated in tcp_connect_to_sock(), but was

not freed in the error exit path. This bug led to a memory leak and an

unresponsive system. A reported case of this bug occurred after running

"cman_tool kill -n [nodename]". (BZ#515432)

 

Users should upgrade to these updated packages, which contain backported

patches to correct these issues. The system must be rebooted for this

update to take effect.

 

4. Solution:

 

Before applying this update, make sure that all previously-released

errata relevant to your system have been applied.

 

This update is available via Red Hat Network. Details on how to use

the Red Hat Network to apply this update are available at

http://kbase.redhat.com/faq/docs/DOC-11259

 

5. Bugs fixed (http://bugzilla.redhat.com/):

 

515432 - dlm_send socket leak [rhel-5.3.z]

516949 - CVE-2009-2692 kernel: uninit op in SOCKOPS_WRAP() leads to privesc

518034 - CVE-2009-2698 kernel: udp socket NULL ptr dereference
