install these updates.

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

take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2015-3636: Memory corruption when unhashing IPv4 ping sockets.

The kernel IPv4 subsystem does not correctly handle unhashing a ping
socket which can trigger kernel memory corruption. A local user can use
this flaw to gain elevated privileges.


* CVE-2015-1805: Memory corruption in handling of userspace pipe I/O vector.

Pipe I/O vector handling functions didn't handle failure of atomic accesses
correctly. This would allow a local unprivileged user to crash the system.


* CVE-2015-4167: Memory corruption when mounting malformed UDF disk images.

The kernel UDF filesystem driver, used by some CD-ROMs and DVDs, does
not validate overly long extended attributes which can trigger kernel
memory corruption and a kernel panic.
