Synopsis:	Important: kernel security, bug fix, and enhancement update
Issue date:	2011-01-04
CVE Names:	CVE-2010-3432 CVE-2010-3442 CVE-2010-3699
                   CVE-2010-3858 CVE-2010-3859 CVE-2010-3865
                   CVE-2010-3876 CVE-2010-3880 CVE-2010-4083
                   CVE-2010-4157 CVE-2010-4161 CVE-2010-4242
                   CVE-2010-4247 CVE-2010-4248

This update fixes the following security issues:

* A flaw was found in sctp_packet_config() in the Linux kernel's Stream
Control Transmission Protocol (SCTP) implementation. A remote attacker
could use this flaw to cause a denial of service. (CVE-2010-3432,
Important)

* A missing integer overflow check was found in snd_ctl_new() in the 
Linux kernel's sound subsystem. A local, unprivileged user on a 32-bit 
system could use this flaw to cause a denial of service or escalate 
their privileges. (CVE-2010-3442, Important)

* A heap overflow flaw in the Linux kernel's Transparent Inter-Process
Communication protocol (TIPC) implementation could allow a local,
unprivileged user to escalate their privileges. (CVE-2010-3859, Important)

* An integer overflow flaw was found in the Linux kernel's Reliable
Datagram Sockets (RDS) protocol implementation. A local, unprivileged 
user could use this flaw to cause a denial of service or escalate their
privileges. (CVE-2010-3865, Important)

* A flaw was found in the Xenbus code for the unified block-device I/O
interface back end. A privileged guest user could use this flaw to cause 
a denial of service on the host system running the Xen hypervisor.
(CVE-2010-3699, Moderate)

* Missing sanity checks were found in setup_arg_pages() in the Linux
kernel. When making the size of the argument and environment area on the
stack very large, it could trigger a BUG_ON(), resulting in a local 
denial of service. (CVE-2010-3858, Moderate)

* A flaw was found in inet_csk_diag_dump() in the Linux kernel's module 
for monitoring the sockets of INET transport protocols. By sending a 
netlink message with certain bytecode, a local, unprivileged user could 
cause a denial of service. (CVE-2010-3880, Moderate)

* Missing sanity checks were found in gdth_ioctl_alloc() in the gdth 
driver in the Linux kernel. A local user with access to "/dev/gdth" on a 
64-bit system could use this flaw to cause a denial of service or 
escalate their privileges. (CVE-2010-4157, Moderate)

* The fix put into kernel-2.6.18-164.el5 introduced a regression. A 
local, unprivileged user could use this flaw to cause a denial of 
service. (CVE-2010-4161, Moderate)

* A NULL pointer dereference flaw was found in the Bluetooth HCI UART
driver in the Linux kernel. A local, unprivileged user could use this 
flaw to cause a denial of service. (CVE-2010-4242, Moderate)

* It was found that a malicious guest running on the Xen hypervisor 
could place invalid data in the memory that the guest shared with the 
blkback and blktap back-end drivers, resulting in a denial of service on 
the host system. (CVE-2010-4247, Moderate)

* A flaw was found in the Linux kernel's CPU time clocks implementation 
for the POSIX clock interface. A local, unprivileged user could use this 
flaw to cause a denial of service. (CVE-2010-4248, Moderate)

* Missing initialization flaws in the Linux kernel could lead to
information leaks. (CVE-2010-3876, CVE-2010-4083, Low)


This update also fixes several bugs and adds an enhancement.

The system must be rebooted for this update to take effect.
