Package        : openssl
CVE ID         : CVE-2015-7575

Karthikeyan Bhargavan and Gaetan Leurent at INRIA discovered a flaw in
the TLS 1.2 protocol which could allow the MD5 hash function to be used
for signing ServerKeyExchange and Client Authentication packets during a
TLS handshake. A man-in-the-middle attacker could exploit this flaw to
conduct collision attacks to impersonate a TLS server or an
authenticated TLS client.

https://www.mitls.org/pages/attacks/SLOTH

For the oldstable distribution (wheezy), this problem has been fixed
in version 1.0.1e-2+deb7u19.

For the stable distribution (jessie), the testing distribution (stretch)
and the unstable distribution (sid), this issue was already addressed in
version 1.0.1f-1.

We recommend that you upgrade your openssl packages.

Package        : openssh
CVE ID         : CVE-2016-0777 CVE-2016-0778
Debian bug     : 810984

The Qualys Security team discovered two vulnerabilities in the roaming
code of the OpenSSH client (an implementation of the SSH protocol
suite).

SSH roaming enables a client, in case an SSH connection breaks
unexpectedly, to resume it at a later time, provided the server also
supports it.

The OpenSSH server doesn't support roaming, but the OpenSSH client
supports it (even though it's not documented) and it's enabled by
default.

CVE-2016-0777

    An information leak (memory disclosure) can be exploited by a rogue
    SSH server to trick a client into leaking sensitive data from the
    client memory, including for example private keys.

CVE-2016-0778

    A buffer overflow (leading to file descriptor leak), can also be
    exploited by a rogue SSH server, but due to another bug in the code
    is possibly not exploitable, and only under certain conditions (not
    the default configuration), when using ProxyCommand, ForwardAgent or
    ForwardX11.

This security update completely disables the roaming code in the OpenSSH
client.

It is also possible to disable roaming by adding the (undocumented)
option 'UseRoaming no' to the global /etc/ssh/ssh_config file, or to the
user configuration in ~/.ssh/config, or by passing -oUseRoaming=no on
the command line.

Users with passphrase-less privates keys, especially in non interactive
setups (automated jobs using ssh, scp, rsync+ssh etc.) are advised to
update their keys if they have connected to an SSH server they don't
trust.

More details about identifying an attack and mitigations will be
available in the Qualys Security Advisory.

For the oldstable distribution (wheezy), these problems have been fixed
in version 1:6.0p1-4+deb7u3.

For the stable distribution (jessie), these problems have been fixed in
version 1:6.7p1-5+deb8u1.

For the testing distribution (stretch) and unstable distribution (sid),
these
problems will be fixed in a later version.

We recommend that you upgrade your openssh packages.

CVE ID         : CVE-2013-4312 CVE-2015-7566 CVE-2015-8767 CVE-2016-0723
                 CVE-2016-0728

Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation or denial-of-service.

CVE-2013-4312

    Tetsuo Handa discovered that it is possible for a process to open
    far more files than the process' limit leading to denial-of-service
    conditions.

CVE-2015-7566

    Ralf Spenneberg of OpenSource Security reported that the visor
    driver crashes when a specially crafted USB device without bulk-out
    endpoint is detected.

CVE-2015-8767

    An SCTP denial-of-service was discovered which can be triggered by a
    local attacker during a heartbeat timeout event after the 4-way
    handshake.

CVE-2016-0723

    A use-after-free vulnerability was discovered in the TIOCGETD ioctl.
    A local attacker could use this flaw for denial-of-service.

CVE-2016-0728

    The Perception Point research team discovered a use-after-free
    vulnerability in the keyring facility, possibly leading to local
    privilege escalation.

For the stable distribution (jessie), these problems have been fixed in
version 3.16.7-ckt20-1+deb8u3.

We recommend that you upgrade your linux packages.
