Detail

Problem Description:

Updated kernel packages that fix one security issue and two bugs are now available for Red Hat Enterprise Linux 5.3 Extended Update Support.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5.3.z 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 fixes the following security issue:

* a use-after-free flaw was found in the tcp_rcv_state_process() function in the Linux kernel TCP/IP protocol suite implementation. If a system using IPv6 had the IPV6_RECVPKTINFO option set on a listening socket, a remote attacker could send an IPv6 packet to that system, causing a kernel panic (denial of service). (CVE-2010-1188, Important)

This update also fixes the following bugs:

* a memory leak occurred when reading files on an NFS file system that was mounted with the "noac" option, causing memory to slowly be consumed. Unmounting the file system did not free the memory. With this update, the memory is correctly freed, which resolves this issue. (BZ#588221)

* the RHSA-2009:0225 update fixed a bug where, in some cases, on systems with the kdump service enabled, pressing Alt+SysRq+C to trigger a crash resulted in a system hang; therefore, the system did not restart and boot the dump-capture kernel as expected; no vmcore file was logged; and the following message was displayed on the console:

BUG: warning at arch/[arch]/kernel/crash.c:[xxx]/nmi_shootdown_cpus() (Not tainted)

The RHSA-2009:0225 update resolved this issue by not calling printk() during a crash. It was later discovered that this fix did not resolve the issue in all cases, since there was one condition where printk() was still being called: at a warning condition inside the mdelay() call.

This update replaces mdelay() calls with udelay(), where such a warning condition does not exist, which fully resolves this issue, allowing Alt+SysRq+C to work as expected. (BZ#588211)

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 all previously-released errata relevant to your system have been applied.

This update is available via the 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

To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.

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

577711 - CVE-2010-1188 kernel: ipv6: skb is unexpectedly freed 588211 - [RHEL5.3 GA] The kernel stalls before starting second kernel when pressing Alt+SysRq+c in graphical console [rhel-5.3.z] 588221 - memory leak when reading from files mounted with nfs mount option 'noac' [rhel-5.3.z]

Description: Use-after-free vulnerability in net/ipv4/tcp_input.c in the Linux kernel 2.6 before 2.6.20, when IPV6_RECVPKTINFO is set on a listening socket, allows remote attackers to cause a denial of service (kernel panic) via a SYN packet while the socket is in a listening (TCP_LISTEN) state, which is not properly handled and causes the skb structure to be freed.

Title: DEPRECATED: ELSA-2010-0178 -- Oracle Enterprise Linux 5.5 kernel security and bug fix update (important)
Description: This update fixes the following security issues: * a race condition was found in the mac80211 implementation, a framework used for writing drivers for wireless devices. An attacker could trigger this flaw by sending a Delete Block ACK (DELBA) packet to a target system, resulting in a remote denial of service. Note: This issue only affected users on 802.11n networks, and that also use the iwlagn driver with Intel wireless hardware. (CVE-2009-4027, Important) * a flaw was found in the gfs2_lock() implementation. The GFS2 locking code could skip the lock operation for files that have the S_ISGID bit (set-group-ID on execution) in their mode set. A local, unprivileged user on a system that has a GFS2 file system mounted could use this flaw to cause a kernel panic. (CVE-2010-0727, Moderate) * a divide-by-zero flaw was found in the ext4 file system code. A local attacker could use this flaw to cause a denial of service by mounting a specially-crafted ext4 file system. (CVE-2009-4307, Low)
