3. Description:

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and
Transport Layer Security (TLS) protocols, as well as a full-strength
general-purpose cryptography library.

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)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

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

5. Bugs fixed (https://bugzilla.redhat.com/):

1384743 – CVE-2016-8610 SSL/TLS: Malformed plain-text ALERT packets could cause remote DoS
1416852 – CVE-2017-3731 openssl: Truncated packet could crash via OOB read
