INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Ubuntu 14.04 Trusty
install these updates.

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

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Denial-of-service in block cache driver on device removal.

Lack of testing a kernel thread had been properly started could lead to an
invalid pointer dereference and kernel panic. A local, privileged user
could use this flaw to cause a denial-of-service.


* CVE-2014-3601: Denial-of-service in KVM page mapping.

The kvm map pages function miscalculates the number of pages in the case
of a mapping failure, which allows guest OS users to (1) cause a denial of
service (host OS memory corruption) or possibly have unspecified other
impact by triggering a large gfn value or (2) cause a denial of service
(host OS memory consumption) by triggering a small gfn value that leads to
permanently pinned pages.


* CVE-2014-5471, CVE-2014-5472: Privilege escalation in ISO filesystem implementation.

The parse_rock_ridge_inode_internal() function in the ISO filesystem driver
does not correctly check relocated directories when processing Rock Ridge
child link tags. An attacker with physical access to the system could use a
specially crafted ISO image to cause a denial of service or, potentially,
escalate their privileges.


* CVE-2014-5077: Remote denial-of-service in SCTP on simultaneous connections.

Linux kernel built with the support for Stream Control Transmission
Protocol is vulnerable to a NULL pointer dereference flaw. It could occur
when simultaneous new connections are initiated between the same pair of
hosts. A remote user/program could use this flaw to crash the system kernel
resulting in denial-of-service.
