install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2014-3144, CVE-2014-3145: Multiple local denial of service vulnerabilities in netlink.

The BPF_S_ANC_NLATTR and BPF_S_ANC_NLATTR_NEST extension implementations
in the sk_run_filter function in net/core/filter.c failed to check whether
a certain length value is sufficiently large, which allows local users to
cause a denial of service (integer underflow and system crash) via crafted
BPF instructions.


* Improved fix for CVE-2014-3153: Local privilege escalation in futex requeueing.

An invalid fix for CVE-2014-3153 could cause correct futex requeue operations
to fail. This update corrects the problem.
