Synopsis: Important: kernel security and bug fix update

Advisory ID: RHSA-2009:0326-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0326.html

Issue date: 2009-04-01

CVE Names: CVE-2008-3528 CVE-2008-5700 CVE-2009-0028

CVE-2009-0269 CVE-2009-0322 CVE-2009-0675

CVE-2009-0676 CVE-2009-0778

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

 

1. Summary:

 

Updated kernel packages that fix several security issues and several bugs

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 (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64

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

 

3. Description:

 

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

operating system.

 

Security fixes:

 

* memory leaks were found on some error paths in the icmp_send()

function in the Linux kernel. This could, potentially, cause the network

connectivity to cease. (CVE-2009-0778, Important)

 

* Chris Evans reported a deficiency in the clone() system call when called

with the CLONE_PARENT flag. This flaw permits the caller (the parent

process) to indicate an arbitrary signal it wants to receive when its child

process exits. This could lead to a denial of service of the parent

process. (CVE-2009-0028, Moderate)

 

* an off-by-one underflow flaw was found in the eCryptfs subsystem. This

could potentially cause a local denial of service when the readlink()

function returned an error. (CVE-2009-0269, Moderate)

 

* a deficiency was found in the Remote BIOS Update (RBU) driver for Dell

systems. This could allow a local, unprivileged user to cause a denial of

service by reading zero bytes from the image_type or packet_size files in

"/sys/devices/platform/dell_rbu/". (CVE-2009-0322, Moderate)

 

* an inverted logic flaw was found in the SysKonnect FDDI PCI adapter

driver, allowing driver statistics to be reset only when the CAP_NET_ADMIN

capability was absent (local, unprivileged users could reset driver

statistics). (CVE-2009-0675, Moderate)

 

* the sock_getsockopt() function in the Linux kernel did not properly

initialize a data structure that can be directly returned to user-space

when the getsockopt() function is called with SO_BSDCOMPAT optname set.

This flaw could possibly lead to memory disclosure.

(CVE-2009-0676, Moderate)

 

* the ext2 and ext3 file system code failed to properly handle corrupted

data structures, leading to a possible local denial of service when read

or write operations were performed on a specially-crafted file system.

(CVE-2008-3528, Low)

 

* a deficiency was found in the libATA implementation. This could,

potentially, lead to a local denial of service. Note: by default, the

"/dev/sg*" devices are accessible only to the root user.

(CVE-2008-5700, Low)

 

Bug fixes:

 

* a bug in aic94xx may have caused kernel panics during boot on some

systems with certain SATA disks. (BZ#485909)

 

* a word endianness problem in the qla2xx driver on PowerPC-based machines

may have corrupted flash-based devices. (BZ#485908)

 

* a memory leak in pipe() may have caused a system deadlock. The workaround

in Section 1.5, Known Issues, of the Red Hat Enterprise Linux 5.3 Release

Notes Updates, which involved manually allocating extra file descriptors to

processes calling do_pipe, is no longer necessary. (BZ#481576)

 

* CPU soft-lockups in the network rate estimator. (BZ#481746)

 

* bugs in the ixgbe driver caused it to function unreliably on some

systems with 16 or more CPU cores. (BZ#483210)

 

* the iwl4965 driver may have caused a kernel panic. (BZ#483206)

 

* a bug caused NFS attributes to not update for some long-lived NFS

mounted file systems. (BZ#483201)

 

* unmounting a GFS2 file system may have caused a panic. (BZ#485910)

 

* a bug in ptrace() may have caused a panic when single stepping a target.

(BZ#487394)

 

* on some 64-bit systems, notsc was incorrectly set at boot, causing slow

gettimeofday() calls. (BZ#488239)

 

* do_machine_check() cleared all Machine Check Exception (MCE) status

registers, preventing the BIOS from using them to determine the cause of

certain panics and errors. (BZ#490433)

 

* scaling problems caused performance problems for LAPI applications.

(BZ#489457)

 

* a panic may have occurred on systems using certain Intel WiFi Link 5000

products when booting with the RF Kill switch on. (BZ#489846)

 

* the TSC is invariant with C/P/T states, and always runs at constant

frequency from now on. (BZ#489310)

 

All 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
