Scientific Linux Security Update : openssl on SL5.x i386/x86_64 (DROWN)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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.
