RedHat: RHSA-2013-0587:01 Moderate: openssl security update
Summary
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 OpenSSL leaked timing information when decrypting
TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites
were used. A remote attacker could possibly use this flaw to retrieve plain
text from the encrypted packets by using a TLS/SSL or DTLS server as a
padding oracle. (CVE-2013-0169)
A NULL pointer dereference flaw was found in the OCSP response verification
in OpenSSL. A malicious OCSP server could use this flaw to crash
applications performing OCSP verification by sending a specially-crafted
response. (CVE-2013-0166)
It was discovered that the TLS/SSL protocol could leak information about
plain text when optional compression was used. An attacker able to control
part of the plain text sent over an encrypted TLS/SSL connection could
possibly use this flaw to recover other portions of the plain text.
(CVE-2012-4929)
Note: This update disables zlib compression, which was previously enabled
in OpenSSL by default. Applications using OpenSSL now need to explicitly
enable zlib compression to use it.
It was found that OpenSSL read certain environment variables even when used
by a privileged (setuid or setgid) application. A local attacker could use
this flaw to escalate their privileges. No application shipped with Red Hat
Enterprise Linux 5 and 6 was affected by this problem. (BZ#839735)
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.
Summary
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
