[Oracle Ksplice]

Synopsis: DSA-2949-1 can now be patched using Ksplice
CVEs: CVE-2014-3144 CVE-2014-3153

Systems running Debian 7.0 Wheezy can now use Ksplice to patch against
the latest Debian Security Advisory, DSA-2949-1.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Debian 7.0 Wheezy
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-2014-3153: Local privilege escalation in futex requeueing.

Invalid parameters to the futex() syscall may break assumptions made in
the kernel and would leave dangling pointers that could be exploited
to gain root privileges.


* CVE-2014-3144: 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.
