Red Hat Security Advisory

 

Synopsis: Important: kernel security update

Advisory ID: RHSA-2009:0264-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0264.html

Issue date: 2009-02-10

CVE Names: CVE-2008-4933 CVE-2008-4934 CVE-2008-5025

CVE-2008-5713 CVE-2009-0031 CVE-2009-0065

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

 

1. Summary:

 

Updated kernel packages that resolve several security issues 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.

 

This update addresses the following security issues:

 

* a memory leak in keyctl handling. A local user could use this flaw to

deplete kernel memory, eventually leading to a denial of service.

(CVE-2009-0031, Important)

 

* a buffer overflow in the Linux kernel Partial Reliable Stream Control

Transmission Protocol (PR-SCTP) implementation. This could, potentially,

lead to a denial of service if a Forward-TSN chunk is received with a large

stream ID. (CVE-2009-0065, Important)

 

* a flaw when handling heavy network traffic on an SMP system with many

cores. An attacker who could send a large amount of network traffic could

create a denial of service. (CVE-2008-5713, Important)

 

* the code for the HFS and HFS Plus (HFS+) file systems failed to properly

handle corrupted data structures. This could, potentially, lead to a local

denial of service. (CVE-2008-4933, CVE-2008-5025, Low)

 

* a flaw was found in the HFS Plus (HFS+) file system implementation. This

could, potentially, lead to a local denial of service when write operations

are performed. (CVE-2008-4934, Low)

 

In addition, these updated packages fix the following bugs:

 

* when using the nfsd daemon in a clustered setup, kernel panics appeared

seemingly at random. These panics were caused by a race condition in

the device-mapper mirror target.

 

* the clock_gettime(CLOCK_THREAD_CPUTIME_ID, ) syscall returned a smaller

timespec value than the result of previous clock_gettime() function

execution, which resulted in a negative, and nonsensical, elapsed time value.

 

* nfs_create_rpc_client was called with a "flavor" parameter which was

usually ignored and ended up unconditionally creating the RPC client with

an AUTH_UNIX flavor. This caused problems on AUTH_GSS mounts when the

credentials needed to be refreshed. The credops did not match the

authorization type, which resulted in the credops dereferencing an

incorrect part of the AUTH_UNIX rpc_auth struct.

 

* when copy_user_c terminated prematurely due to reading beyond the end of

the user buffer and the kernel jumped to the exception table entry, the rsi

register was not cleared. This resulted in exiting back to user code with

garbage in the rsi register.

 

* the hexdump data in s390dbf traces was incomplete. The length of the data

traced was incorrect and the SAN payload was read from a different place

then it was written to.

 

* when using connected mode (CM) in IPoIB on ehca2 hardware, it was not

possible to transmit any data.

 

* when an application called fork() and pthread_create() many times and, at

some point, a thread forked a child and then attempted to call the

setpgid() function, then this function failed and returned and ESRCH error

value.

 

Users should upgrade to these updated packages, which contain backported

patches to correct these issues. Note: for this update to take effect, the

system must be rebooted.

 

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
