GLSA 201407-05: OpenSSL: Multiple vulnerabilities

http://security.gentoo.org/

Severity:	high
Title:	OpenSSL: Multiple vulnerabilities
Date:	07/27/2014
Bugs:	#512506
ID:	201407-05

Synopsis

Multiple vulnerabilities have been found in OpenSSL, possibly allowing remote attackers to execute arbitrary code.

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.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-libs/openssl	< 1.0.1h-r1	>= 1.0.1h-r1	All supported architectures

Description

Multiple vulnerabilities have been discovered in OpenSSL. Please review the OpenSSL Security Advisory [05 Jun 2014] and the CVE identifiers referenced below for details.

Impact

A remote attacker could send specially crafted DTLS fragments to an OpenSSL DTLS client or server to possibly execute arbitrary code with the privileges of the process using OpenSSL.

Furthermore, an attacker could force the use of weak keying material in OpenSSL SSL/TLS clients and servers, inject data across sessions, or cause a Denial of Service via various vectors.

Workaround

There is no known workaround at this time.

Resolution

All OpenSSL users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.1h-r1"
