Title: OpenSSL: Multiple vulnerabilities (GLSA 201601-05)
Severity: normal
Exploitable: remote
Date: January 29, 2016
Updated: February 26, 2016
Bug(s): #572854
ID: 201601-05

Synopsis

Multiple vulnerabilities have been found in OpenSSL, allowing
remote attackers to disclose sensitive information and complete weak
handshakes.


Background

OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general
purpose cryptography library.

Description

Multiple vulnerabilities have been discovered in OpenSSL. Please review
the upstream advisory and CVE identifiers referenced below for details.
Note that the list includes CVE identifiers for an older OpenSSL Security
Advisory (3 Dec 2015) for which we have not issued a GLSA before.


Impact

A remote attacker could disclose a server’s private DH exponent, or
complete SSLv2 handshakes using ciphers that have been disabled on the
server.


Workaround

There is no known workaround at this time.

Resolution

All OpenSSL users should upgrade to the latest version:
