Scientific Linux Security Update : openssl on SL5.x i386/x86_64 (20160301) (DROWN)
high Nessus Plugin ID 89074
Language:
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.
Solution
