updates.

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

DESCRIPTION

* CVE-2014-3215: Privilege escalation in seunshare execution of binaries.

A bug in libcap-ng could allow local, unpriviliged users to potentially
escalate priviliges on a system, exploitable through seunshare and other
tools.


* CVE-2014-9529: Use-after-free when garbage collecting keys.

A logic error when garbage collecting cryptographic keys leads to a
user-after-free and kernel panic. A local user could use this flaw to crash
the kernel and cause a denial-of-service.


* CVE-2014-9584: Out-of-bounds memory access in ISO filesystem when printing ER records.

A missing input validation when printing ER records on the iso9660 driver
could lead to an out-of-bounds memory write, potentially leading to a
kernel panic.  A local attacker could use a corrupted ISO file to cause a
denial-of-service.
