linux-ec2 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ec2: Linux kernel for EC2

Details:

Mathias Krause discovered an information leak in the Linux kernel's
getsockname implementation for Logical Link Layer (llc) sockets. A local
user could exploit this flaw to examine some of the kernel's stack memory.
(CVE-2012-6542)

Mathias Krause discovered information leaks in the Linux kernel's Bluetooth
Logical Link Control and Adaptation Protocol (L2CAP) implementation. A
local user could exploit these flaws to examine some of the kernel's stack
memory. (CVE-2012-6544)

Mathias Krause discovered information leaks in the Linux kernel's Bluetooth
RFCOMM protocol implementation. A local user could exploit these flaws to
examine parts of kernel memory. (CVE-2012-6545)

Mathias Krause discovered information leaks in the Linux kernel's
Asynchronous Transfer Mode (ATM) networking stack. A local user could
exploit these flaws to examine some parts of kernel memory. (CVE-2012-6546)

Mathias Krause discovered an information leak in the Linux kernel's UDF
file system implementation. A local user could exploit this flaw to examine
some of the kernel's heap memory. (CVE-2012-6548)

Andrew Jones discovered a flaw with the xen_iret function in Linux kernel's
Xen virtualizeation. In the 32-bit Xen paravirt platform an unprivileged
guest OS user could exploit this flaw to cause a denial of service (crash
the system) or gain guest OS privilege. (CVE-2013-0228)

An information leak was discovered in the Linux kernel's Bluetooth stack
when HIDP (Human Interface Device Protocol) support is enabled. A local
unprivileged user could exploit this flaw to cause an information leak from
the kernel. (CVE-2013-0349)

A flaw was discovered in the Edgeort USB serial converter driver when the
device is disconnected while it is in use. A local user could exploit this
flaw to cause a denial of service (system crash). (CVE-2013-1774)

Andrew Honig discovered a flaw in guest OS time updates in the Linux
kernel's KVM (Kernel-based Virtual Machine). A privileged guest user could
exploit this flaw to cause a denial of service (crash host system) or
potential escalate privilege to the host kernel level. (CVE-2013-1796)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 10.04 LTS:
linux-image-2.6.32-351-ec2 2.6.32-351.64

After a standard system update you need to reboot your computer to make
all the necessary changes.
