Test ID:1.3.6.1.4.1.25623.1.0.70666
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2012:0060
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2012:0060.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols, as well as a
full-strength, general purpose cryptography library.

It was discovered that the Datagram Transport Layer Security (DTLS)
protocol implementation in OpenSSL leaked timing information when
performing certain operations. A remote attacker could possibly use this
flaw to retrieve plain text from the encrypted packets by using a DTLS
server as a padding oracle. (CVE-2011-4108)

A double free flaw was discovered in the policy checking code in OpenSSL.
A remote attacker could use this flaw to crash an application that uses
OpenSSL by providing an X.509 certificate that has specially-crafted
policy extension data. (CVE-2011-4109)

An information leak flaw was found in the SSL 3.0 protocol implementation
in OpenSSL. Incorrect initialization of SSL record padding bytes could
cause an SSL client or server to send a limited amount of possibly
sensitive data to its SSL peer via the encrypted connection.
(CVE-2011-4576)

It was discovered that OpenSSL did not limit the number of TLS/SSL
handshake restarts required to support Server Gated Cryptography. A remote
attacker could use this flaw to make a TLS/SSL server using OpenSSL consume
an excessive amount of CPU by continuously restarting the handshake.
(CVE-2011-4619)

All OpenSSL users should upgrade to these updated packages, which contain
backported patches to resolve these issues. For the update to take effect,
all services linked to the OpenSSL library must be restarted, or the system
rebooted.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
