Synopsis: Important: kernel security and bug fix update
Issue date: 2010-03-16
CVE Names: CVE-2009-4271 CVE-2010-0003 CVE-2010-0007
CVE-2010-0008 CVE-2010-0307
This update fixes the following security issues:
* 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 Linux kernel. During
a core dump, the kernel did not check if the Virtual Dynamically-linked
Shared Object page was accessible. On Intel 64 and AMD64 systems, a
local, unprivileged user could use this flaw to cause a kernel panic by
running a crafted 32-bit application. (CVE-2009-4271, Important)
* an information leak was found in the print_fatal_signal()
implementation in the Linux kernel. When
"/proc/sys/kernel/print-fatal-signals" is set to 1 (the default value is
0), memory that is reachable by the kernel could be leaked to
user-space. This issue could also result in a system crash. Note that
this flaw only affected the i386 architecture. (CVE-2010-0003,
Moderate)
* on AMD64 systems, it was discovered that the kernel did not ensure the
ELF interpreter was available before making a call to the
SET_PERSONALITY macro. A local attacker could use this flaw to cause a
denial of service by running a 32-bit application that attempts to
execute a 64-bit application. (CVE-2010-0307, Moderate)
* missing capability checks were found in the ebtables implementation,
used for creating an Ethernet bridge firewall. This could allow a local,
unprivileged user to bypass intended capability restrictions and modify
ebtables rules. (CVE-2010-0007, Low)
This update also fixes the following bugs:
* under some circumstances, a locking bug could have caused an online
ext3 file system resize to deadlock, which may have, in turn, caused the
file system or the entire system to become unresponsive. In either case,
a reboot was required after the deadlock. With this update, using
resize2fs to perform an online resize of an ext3 file system works as
expected. (BZ#553135)
* some ATA and SCSI devices were not honoring the barrier=1 mount
option, which could result in data loss after a crash or power loss.
This update applies a patch to the Linux SCSI driver to ensure ordered
write caching. This solution does not provide cache flushes; however, it
does provide data integrity on devices that have no write caching (or
where write caching is disabled) and no command queuing. For systems
that have command queuing or write cache enabled there is no guarantee
of data integrity after a crash. (BZ#560563)
* it was found that lpfc_find_target() could loop continuously when
scanning a list of nodes due to a missing spinlock. This missing
spinlock allowed the list to be changed after the list_empty() test,
resulting in a NULL value, causing the loop. This update adds the
spinlock, resolving the issue. (BZ#561453)
* the fix for CVE-2009-4538 provided by RHSA-2010:0020 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#565496)
The system must be rebooted for this update to take effect.
