Detail

Problem Description:

Updated kernel packages that fix two security issues, three bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

* A flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled TCP packets with both the SYN and FIN flags set. A remote attacker could use this flaw to consume an excessive amount of resources on the target system, potentially resulting in a denial of service. (CVE-2012-6638, Moderate)

* A flaw was found in the way the Linux kernel handled HID (Human Interface Device) reports with an out-of-bounds Report ID. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-2888, Moderate)

This update also fixes the following bugs:

* A previous change to the sunrpc code introduced a race condition between the rpc_wake_up_task() and rpc_wake_up_status() functions. A race between threads operating on these functions could result in a deadlock situation, subsequently triggering a "soft lockup" event and rendering the system unresponsive. This problem has been fixed by re-ordering tasks in the RPC wait queue. (BZ#1073731)

* Running a process in the background on a GFS2 file system could sometimes trigger a glock recursion error that resulted in a kernel panic. This happened when a readpage operation attempted to take a glock that had already been held by another function. To prevent this error, GFS2 now verifies whether the glock is already held when performing the readpage operation. (BZ#1073953)

* A previous patch backport to the IUCV (Inter User Communication Vehicle) code was incomplete. Consequently, when establishing an IUCV connection, the kernel could, under certain circumstances, dereference a NULL pointer, resulting in a kernel panic. A patch has been applied to correct this problem by calling the proper function when removing IUCV paths. (BZ#1077045)

In addition, this update adds the following enhancement:

* The lpfc driver had a fixed timeout of 60 seconds for SCSI task management commands. With this update, the lpfc driver enables the user to set this timeout within the range from 5 to 180 seconds. The timeout can be changed by modifying the "lpfc_task_mgmt_tmo" parameter for the lpfc driver. (BZ#1073123)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement. 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 https://access.redhat.com/site/articles/11258

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 (https://bugzilla.redhat.com/):

1000451 - CVE-2013-2888 Kernel: HID: memory corruption flaw 1066055 - CVE-2012-6638 Kernel: net: tcp: potential DoS via SYN+FIN messages
