Systems running Ubuntu 12.04 Precise can now use Ksplice to patch
against the latest Ubuntu Security Notice, USN-2996-1.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Ubuntu 12.04 Precise
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

IMPORTANT NOTE

The Ksplice update fixing CVE-2016-1583 will not apply it there are any
mounted eCryptfs filesystem.  Please unmount them temporarily whilst
running uptrack-upgrade.


DESCRIPTION

* CVE-2016-3955: Privilege escalation in IP over USB driver.

Missing user supplied input validation could result in an out-of-bounds
write allowing a local user to crash the system or potentially escalate
privileges.


* CVE-2016-3672: ASLR bypass on 32-bit processes.

Enabling an unlimited stack size would completely disable ASLR for
process with the limit applied.  A local user could use this flaw to
reduce the security of a setuid/setgid application.


* CVE-2016-2185: Denial of service in ATI/Philips USB RF remote descriptor parsing.

A logic error in the ATI/Philips USB RF remote driver can allow a
malformed USB descriptor to trigger a NULL pointer dereference and
kernel panic.


* CVE-2016-2186: Denial of service in Griffin PowerMate USB descriptor parsing.

A logic error in the Griffin PowerMate USB driver can allow a malformed
USB descriptor with zero endpoints to trigger a NULL pointer dereference
and kernel panic.


* CVE-2016-2188: Denial of service in IO Warrior USB descriptor parsing.

A logic error in the IO Warrior USB driver can allow a malformed USB
descriptor with zero endpoints to trigger a NULL pointer dereference and
kernel panic.


* CVE-2016-3138: Denial of service in CDC ADM USB descriptor parsing.

A logic error in the CDC ADM USB driver can allow a malformed USB
descriptor with an incorrect number of interfaces to trigger a NULL
pointer dereference and kernel panic.


* CVE-2016-3156: Denial-of-service when removing a network interface.

Removal of a network interface with lots of IPv4 addresses may lead to the
kernel hanging for a long time, with all network operation blocked.  A
local, privileged user in a container could use this flaw to block network
access and cause a denial-of-service.


* CVE-2016-3157: Xen I/O port access privilege escalation in x86-64.

User mode processes not supposed to be able to access I/O ports may
be granted such permission, potentially resulting in one or more of
in-guest privilege escalation, guest crashes (Denial of Service), or
in-guest information leaks.


* CVE-2016-2184: Denial of service in ALSA USB audio descriptor parsing.

A logic error in the ALSA USB audio driver can allow a malformed USB
descriptor with zero end-points to trigger a NULL pointer dereference
and kernel panic.


* CVE-2016-3136: Denial of service in MCT Serial USB descriptor parsing.

A logic error in the MCT Single Port Serial driver can allow a malformed
USB descriptor with missing ports to trigger a NULL pointer dereference
and kernel panic.


* CVE-2016-3137: Denial of service in USB Cypress M8 descriptor parsing.

A logic error in the Cypress M8 device driver can allow a malformed USB
descriptor with missing endpoints to trigger a NULL pointer dereference
and kernel panic.


* CVE-2016-3140: Denial of service in Digi AccelePort USB descriptor parsing.

A logic error in the Digi AccelePort USB driver can allow a malformed
USB descriptor with missing endpoints to trigger a NULL pointer
dereference and kernel panic.


* CVE-2016-2187: Denial of service in GTCO CallComp/InterWrite USB descriptor parsing.

A logic error in the GTCO CallComp/InterWrite USB driver can allow a
malformed USB descriptor with zero endpoints to trigger a NULL pointer
dereference and kernel panic.


* CVE-2016-4485: Information leak in LLC message processing.

The Logical Link Layer networking driver does not initialize memory when
proesssing ancillary data requests to an LLC socket which leaks the
contents of kernel memory to userspace. A local user could use this flaw
to infer the layout of kernel memory.


* CVE-2016-4486: Information leak in routing netlink interface.

The netlink interface for querying network routing information does not
initialize memory which leaks the contents of kernel memory to userspace.
A local user could use this flaw to infer the layout of kernel memory.


* CVE-2016-1583: Privilege escalation in eCryptfs.

eCryptfs was incorrectly trying to use the mmap() file operation on lower
filesystem that may not support it.  A local, unprivileged user could use
this flaw to cause a denial-of-service through recursive faults or
potentially escalate privileges.
