Security fixes:
* The maximum file offset handling for ext4 file systems could allow a
local, unprivileged user to cause a denial of service. (CVE-2011-2695,
Important)
* IPv6 fragment identification value generation could allow a remote
attacker to disrupt a target system's networking, preventing legitimate
users from accessing its services. (CVE-2011-2699, Important)
* A malicious CIFS (Common Internet File System) server could send a
specially-crafted response to a directory read request that would result in
a denial of service or privilege escalation on a system that has a CIFS
share mounted. (CVE-2011-3191, Important)
* A local attacker could use mount.ecryptfs_private to mount (and then
access) a directory they would otherwise not have access to. Note: To
correct this issue, the RHSA-2011:1241 ecryptfs-utils update must also be
installed. (CVE-2011-1833, Moderate)
* A flaw in the taskstats subsystem could allow a local, unprivileged user
to cause excessive CPU time and memory use. (CVE-2011-2484, Moderate)
* Mapping expansion handling could allow a local, unprivileged user to
cause a denial of service. (CVE-2011-2496, Moderate)
* GRO (Generic Receive Offload) fields could be left in an inconsistent
state. An attacker on the local network could use this flaw to cause a
denial of service. GRO is enabled by default in all network drivers that
support it. (CVE-2011-2723, Moderate)
* RHSA-2011:1065 introduced a regression in the Ethernet bridge
implementation. If a system had an interface in a bridge, and an attacker
on the local network could send packets to that interface, they could cause
a denial of service on that system. Xen hypervisor and KVM (Kernel-based
Virtual Machine) hosts often deploy bridge interfaces. (CVE-2011-2942,
Moderate)
* A flaw in the Xen hypervisor IOMMU error handling implementation could
allow a privileged guest user, within a guest operating system that has
direct control of a PCI device, to cause performance degradation on the
host and possibly cause it to hang. (CVE-2011-3131, Moderate)
* IPv4 and IPv6 protocol sequence number and fragment ID generation could
allow a man-in-the-middle attacker to inject packets and possibly hijack
connections. Protocol sequence number and fragment IDs are now more random.
(CVE-2011-3188, Moderate)
* A flaw in the kernel's clock implementation could allow a local,
unprivileged user to cause a denial of service. (CVE-2011-3209, Moderat ...
