Synopsis:          Important: openssl security update
Advisory ID:       SLSA-2016:0302-1
Issue Date:        2016-03-01
CVE Numbers:       CVE-2015-3197
                   CVE-2016-0800
                   CVE-2016-0797
--

A padding oracle flaw was found in the Secure Sockets Layer version 2.0
(SSLv2) protocol. An attacker can potentially use this flaw to decrypt
RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol
version, allowing them to decrypt such connections. This cross-protocol
attack is publicly referred to as DROWN. (CVE-2016-0800)

A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2
ciphers that have been disabled on the server. This could result in weak
SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to
man-in-the-middle attacks. (CVE-2015-3197)

An integer overflow flaw, leading to a NULL pointer dereference or a heap-
based memory corruption, was found in the way some BIGNUM functions of
OpenSSL were implemented. Applications that use these functions with large
untrusted input could crash or, potentially, execute arbitrary code.
(CVE-2016-0797)

For the update to take effect, all services linked to the OpenSSL library
must be restarted, or the system rebooted.
