This update fixes the following security issues:
* Using PCI passthrough without interrupt remapping support allowed Xen
hypervisor guests to generate MSI interrupts and thus potentially inject
traps. A privileged guest user could use this flaw to crash the host or
possibly escalate their privileges on the host. The fix for this issue can
prevent PCI passthrough working and guests starting. Refer to Red Hat
Bugzilla bug 715555 for details. (CVE-2011-1898, Important)
* A flaw was found in the way CIFS (Common Internet File System) shares
with DFS referrals at their root were handled. An attacker on the local
network who is able to deploy a malicious CIFS server could create a CIFS
network share that, when mounted, would cause the client system to crash.
(CVE-2011-3363, Moderate)
* A NULL pointer dereference flaw was found in the way the Linux kernel's
key management facility handled user-defined key types. A local,
unprivileged user could use the keyctl utility to cause a denial of
service. (CVE-2011-4110, Moderate)
* A flaw in the way memory containing security-related data was handled in
tpm_read() could allow a local, unprivileged user to read the results of a
previously run TPM command. (CVE-2011-1162, Low)
* A NULL pointer dereference flaw was found in the Linux kernel's HFS file
system implementation. A local attacker could use this flaw to cause a
denial of service by mounting a disk that contains a specially-crafted HFS
file system with a corrupted MDB extent record. (CVE-2011-2203, Low)
* The I/O statistics from the taskstats subsystem could be read without
any restrictions. A local, unprivileged user could use this flaw to gather
confidential information, such as the length of a password used in a
process. (CVE-2011-2494, Low)
Red Hat would like to thank Yogesh Sharma for reporting CVE-2011-3363,
Peter Huewe for reporting CVE-2011-1162, Clement Lecigne for reporting
CVE-2011-2203, and Vasiliy Kulikov of Openwall for reporting CVE-2011-2494.
This update also fixes several bugs and adds one enhancement. Documentation
for these changes will be available shortly from the Technical Notes
document linked to in the References section.
Users should upgrade to these updated packages, which contain backported
patches to correct these issues, and fix the bugs and add the enhancement
noted in the Technical Notes. The system must be rebooted for this update
to take effect.");
