Synopsis: Moderate: openssl security update
Advisory ID: SLSA-2017:0286-1
Issue Date: 2017-02-20
CVE Numbers: CVE-2016-8610
 CVE-2017-3731
--

Security Fix(es):

* An integer underflow leading to an out of bounds read flaw was found in
OpenSSL. A remote attacker could possibly use this flaw to crash a 32-bit
TLS/SSL server or client using OpenSSL if it used the RC4-MD5 cipher
suite. (CVE-2017-3731)

* A denial of service flaw was found in the way the TLS/SSL protocol
defined processing of ALERT packets during a connection handshake. A
remote attacker could use this flaw to make a TLS/SSL server consume an
excessive amount of CPU and fail to accept connections form other clients.
(CVE-2016-8610)
