[Ksplice][Debian 8.0 Updates] New updates available via Ksplice (DSA 3659-1)

[Oracle Ksplice]

Synopsis: DSA 3659-1 can now be patched using Ksplice
CVEs: CVE-2016-0758 CVE-2016-2188 CVE-2016-3689 CVE-2016-5696 CVE-2016-6480 CVE-2016-6828

Systems running Debian 8.0 Jessie can now use Ksplice to patch against
the latest Debian kernel update, DSA 3659-1.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Debian 8.0 Jessie
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


DESCRIPTION

* 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-2016-3689: Denial of service in IMS PCU USB descriptor parsing.

A logic error in the IMS PCU USB driver can allow a malformed USB
descriptor with missing interfaces to trigger a NULL pointer dereference
and kernel panic.


* CVE-2016-0758: Privilege escalation in ASN.1 DER decoder.

A flaw in the ASN.1 DER decoder could allow a local, unprivileged user
to use a maliciously crafted X.509 certificate DER file to crash the
system or, potentially, escalate privileges.


* Information leak in 'environ' procfs file.

A race condition when forking a process can allow another process to
access the 'environ' file before it is initialized which can leak the
contents of kernel memory.


* Memory corruption when inserting data into associative arrays.

A logic error in the generic associative array module can trigger an
out-of-bounds read when inserting a new member. This can be triggered,
for example, by inserting a new cryptographic key into the kernel's
keyring.


* Denial-of-service in recvmmsg() error handling.

Incorrect reference counting could result in a use-after-free in the
recvmmsg() system call.  A local, unprivileged user could use this flaw
to trigger a denial-of-service.


* CVE-2016-5696: Session hijacking in TCP connections.

A logic error in the core TCP subsystem can allow attackers to easily
guess secret information and inject arbitrary packets into a TCP stream.


* CVE-2016-6828: Use after free during TCP transmission.

A logic error when a memory allocation fails during TCP transmission can
cause the kernel TCP stack to use freed memory causing a kernel panic.


* CVE-2016-6480: Denial-of-service in Adaptec AACRAID driver.

A race condition in fetching parameters from userspace could result in
accessing beyond the bounds of a buffer.  A local user with privileges
to access the device could use this flaw to crash the system.
