Updated kernel packages that fix three security issues and multiple 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. 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.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

  • a deficiency was found in the fasync_helper() implementation. This could allow a local, unprivileged user to leverage a use-after-free of locked, asynchronous file descriptors to cause a denial of service or privilege escalation. (CVE-2009-4141, Important)

  • a NULL pointer dereference flaw was found in the sctp_rcv_ootb() function in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. A remote attacker could send a specially crafted SCTP packet to a target system, resulting in a denial of service. (CVE-2010-0008, Important)

  • a NULL pointer dereference flaw was found in the ip6_dst_lookup_tail() function in the Linux kernel. An attacker on the local network could trigger this flaw by sending IPv6 traffic to a target system, leading to a system crash (kernel OOPS) if dst->neighbour is NULL on the target system when receiving an IPv6 packet. (CVE-2010-0437, Important)

This update also fixes the following bugs :

  • programs compiled on x86, and that also call sched_rr_get_interval(), were silently corrupted when run on 64-bit systems. With this update, when such programs attempt to call sched_rr_get_interval() on 64-bit systems, sys32_sched_rr_get_interval() is called instead, which resolves this issue. (BZ#557683)

  • the fix for CVE-2009-4538 provided by RHSA-2010:0053 introduced a regression, preventing Wake on LAN (WoL) working for network devices using the Intel PRO/1000 Linux driver, e1000e. Attempting to configure WoL for such devices resulted in the following error, even when configuring valid options :

‘Cannot set new wake-on-lan settings: Operation not supported not setting wol’

This update resolves this regression, and WoL now works as expected for network devices using the e1000e driver. (BZ#559334)

  • a number of bugs have been fixed in the copy_user routines for Intel 64 and AMD64 systems, one of which could have possibly led to data corruption. (BZ#568307)

  • on some systems, a race condition in the inode-based file event notifications implementation caused soft lockups and the following messages :

‘BUG: warning at fs/inotify.c:181/set_dentry_child_flags()’ ‘BUG: soft lockup - CPU#[x] stuck for 10s!’

This update resolves this race condition, and also removes the inotify debugging code from the kernel, due to race conditions in that code.
(BZ#568663)

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.
