[SE-2014-02] Google App Engine Java security sandbox bypasses (Issue 42)

Posted by Security Explorations on Oct 21

Hello All,

Oracle Critical Patch Update released yesterday incorporates a fix
for a Java SE 7 vulnerability (Issue 42) that was discovered while
investigating security of Google App Engine. Its technical details
and a POC code can be found at the following address:

Issue 42 is caused by improper initialization of interface method
slots in a HotSpot VM. As a result, protected…

USN-2773-1: Linux kernel vulnerabilities

Ubuntu Security Notice USN-2773-1

19th October, 2015

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

It was discovered that virtio networking in the Linux kernel did not handle
fragments correctly, leading to kernel memory corruption. A remote attacker
could use this to cause a denial of service (system crash) or possibly
execute code with administrative privileges. (CVE-2015-5156)

It was discovered that the Reliable Datagram Sockets (RDS) implementation
in the Linux kernel did not verify sockets were properly bound before
attempting to send a message, which could cause a NULL pointer dereference.
An attacker could use this to cause a denial of service (system crash).
(CVE-2015-6937)

Update instructions

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-92-virtual

3.2.0-92.130
linux-image-3.2.0-92-generic-pae

3.2.0-92.130
linux-image-3.2.0-92-powerpc-smp

3.2.0-92.130
linux-image-3.2.0-92-powerpc64-smp

3.2.0-92.130
linux-image-3.2.0-92-omap

3.2.0-92.130
linux-image-3.2.0-92-generic

3.2.0-92.130
linux-image-3.2.0-92-highbank

3.2.0-92.130

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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.

USN-2775-1: Linux kernel (Trusty HWE) vulnerabilities

Ubuntu Security Notice USN-2775-1

19th October, 2015

linux-lts-trusty 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-lts-trusty
    – Linux hardware enablement kernel from Trusty

Details

It was discovered that the Linux kernel did not check if a new IPv6 MTU set
by a user space application was valid. A remote attacker could forge a
route advertisement with an invalid MTU that a user space daemon like
NetworkManager would honor and apply to the kernel, causing a denial of
service. (CVE-2015-0272)

It was discovered that virtio networking in the Linux kernel did not handle
fragments correctly, leading to kernel memory corruption. A remote attacker
could use this to cause a denial of service (system crash) or possibly

attempting to send a message, which could cause a NULL pointer dereference.
An attacker could use this to cause a denial of service (system crash).
(CVE-2015-6937)

Ben Hutchings discovered that the Advanced Union Filesystem (aufs) for the
Linux kernel did not correctly handle references of memory mapped files
from an aufs mount. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code with
administrative privileges. (CVE-2015-7312)

Update instructions

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

Ubuntu 12.04 LTS:
