On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

Alternatively, you can install these updates by running:

DESCRIPTION

* CVE-2013-0914: Information leak in signal handlers.

A logic error in the handling of signal handlers allows a child process to
leak information about the memory layout of parent processes.


* CVE-2013-1767: Use-after-free in tmpfs mempolicy remount.

If a tempfs mount that was originally mounted with the mpol=M
option is remounted it reuses the already freed mempolicy object.


* CVE-2013-1792: Denial-of-service in user keyring management.

A race condition in installing a user keyring could allow a local,
unprivileged user to crash the machine causing a denial-of-service.


* CVE-2012-6537: Kernel information leaks in network transformation subsystem.

This fixes several cases where xfrm_user code could lead kernel
memory to user space.


* CVE-2012-6539: Information leak in socket compatibility ioctl.

The SIOCGIFCONF socket option allows malicious users to disclose the
contents of kernel memory.


* CVE-2012-6540: Information leak in IP Virtual Server socket options.

A malicious user can disclose the contents of kernel memory by calling
getsockopt() on an IP virtual server socket.
