Ubuntu Security Notice USN-1694-1
January 17, 2013

rpm vulnerability
==========================================================================

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

- Ubuntu 12.10

Summary:

RPM could incorrectly validate package signatures.

Software Description:
- rpm: package manager for RPM

Details:

It was discovered that RPM incorrectly handled signature checking. An
attacker could create a specially-crafted rpm with an invalid signature
which could pass the signature validation check.

Update instructions:

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

Ubuntu 12.10:
rpm 4.10.0-4ubuntu0.1

In general, a standard system update will make all the necessary changes.

Ubuntu Security Notice USN-1695-1
January 17, 2013

rpm vulnerabilities
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

RPM could be made to crash or run programs if it opened a specially crafted
package file.

Software Description:
- rpm: package manager for RPM

Details:

It was discovered that RPM incorrectly handled certain package headers. If
a user or automated system were tricked into installing a specially crafted
RPM package, an attacker could cause RPM to crash, resulting in a denial of
service, or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 12.04 LTS:
rpm 4.9.1.1-1ubuntu0.1

Ubuntu 11.10:
rpm 4.9.0-7ubuntu0.1

Ubuntu 10.04 LTS:
rpm 4.7.2-1lubuntu0.1

In general, a standard system update will make all the necessary changes.

Ubuntu Security Notice USN-1696-1
January 18, 2013

linux vulnerabilities
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

Jon Howell reported a flaw in the Linux kernel's KVM (Kernel-based virtual
machine) subsystem's handling of the XSAVE CPU feature. On hosts without the
XSAVE CPU feature, using qemu userspace, an unprivileged local attacker could
exploit this flaw to crash the system. (CVE-2012-4461)

A flaw was discovered in the Linux kernel's handling of script execution
when module loading is enabled. A local attacker could exploit this flaw to
cause a leak of kernel stack contents. (CVE-2012-4530)

Florian Weimer discovered that hypervkvpd, which is distributed in the
Linux kernel, was not correctly validating source addresses of netlink
packets. An untrusted local user can cause a denial of service by causing
hypervkvpd to exit. (CVE-2012-5532)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-36-generic 3.2.0-36.57
linux-image-3.2.0-36-generic-pae 3.2.0-36.57
linux-image-3.2.0-36-highbank 3.2.0-36.57
linux-image-3.2.0-36-omap 3.2.0-36.57
linux-image-3.2.0-36-powerpc-smp 3.2.0-36.57
linux-image-3.2.0-36-powerpc64-smp 3.2.0-36.57
linux-image-3.2.0-36-virtual 3.2.0-36.57

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

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
