install these updates.

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

DESCRIPTION

* 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-2015-4700: Denial-of-service in the BSD Packet Filter just-in-time compiler.

A logic error in the BSD Packet Filter (BPF) just-in-time (jit) compiler
could lead the jit'ed program to contain only software breakpoints instead
of the intended opcodes.  A local, privileged user could use this flaw to
cause a denial-of-service by using a specially crafted BPF program.
