GLSA-201203-12 : OpenSSL: Multiple vulnerabilities

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-201203-12
(OpenSSL: Multiple vulnerabilities)

Multiple vulnerabilities have been found in OpenSSL:
Timing differences for decryption are exposed by CBC mode encryption
in OpenSSL&rsquo
s implementation of DTLS (CVE-2011-4108).
A policy check failure can result in a double-free error when
X509_V_FLAG_POLICY_CHECK is set (CVE-2011-4109).
Clients and servers using SSL 3.0 handshakes do not clear the block
cipher padding, allowing a record to contain up to 15 bytes of
uninitialized memory, which could include sensitive information
Assertion errors can occur during the handling of malformed X.509
certificates when OpenSSL is built with RFC 3779 support
A resource management error can occur when OpenSSL&rsquo
s server gated
cryptography (SGC) does not properly handle handshake restarts
Invalid parameters in the GOST block cipher are not properly handled
by the GOST ENGINE(CVE-2012-0027).
An incorrect fix for CVE-2011-4108 creates an unspecified
vulnerability for DTLS applications using OpenSSL (CVE-2012-0050).

Impact :

A remote attacker may be able to cause a Denial of Service or obtain
sensitive information, including plaintext passwords.

Workaround :

There is no known workaround at this time.

Solution :

All OpenSSL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-libs/openssl-1.0.0g'

Risk factor :

High / CVSS Base Score : 9.3
CVSS Temporal Score : 8.1
Public Exploit Available : false
