Red Hat Security Advisory
Synopsis: Moderate: openssl security update
Advisory ID: RHSA-2010:0054-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0054.html
Issue date: 2010-01-19
CVE Names: CVE-2009-2409 CVE-2009-4355
================================================== ===================
1. Summary:
Updated openssl packages that fix two security issues are now available for
Red Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
3. Description:
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 found that the OpenSSL library did not properly re-initialize its
internal state in the SSL_library_init() function after previous calls to
the CRYPTO_cleanup_all_ex_data() function, which would cause a memory leak
for each subsequent SSL connection. This flaw could cause server
applications that call those functions during reload, such as a combination
of the Apache HTTP Server, mod_ssl, PHP, and cURL, to consume all available
memory, resulting in a denial of service. (CVE-2009-4355)
Dan Kaminsky found that browsers could accept certificates with MD2 hash
signatures, even though MD2 is no longer considered a cryptographically
strong algorithm. This could make it easier for an attacker to create a
malicious certificate that would be treated as trusted by a browser.
OpenSSL now disables the use of the MD2 algorithm inside signatures by
default. (CVE-2009-2409)
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.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at

3. Description:
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.
A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure
Sockets Layer) protocols handled session renegotiation. A man-in-the-middle
attacker could use this flaw to prefix arbitrary plain text to a client's
session (for example, an HTTPS connection to a website). This could force
the server to process an attacker's request as if authenticated using the
victim's credentials. This update addresses this flaw by implementing the
TLS Renegotiation Indication Extension, as defined in RFC 5746.
(CVE-2009-3555)
Refer to the following Knowledgebase article for additional details about
the CVE-2009-3555 flaw: http://kbase.redhat.com/faq/docs/DOC-20491
Dan Kaminsky found that browsers could accept certificates with MD2 hash
signatures, even though MD2 is no longer considered a cryptographically
strong algorithm. This could make it easier for an attacker to create a
malicious certificate that would be treated as trusted by a browser.
OpenSSL now disables the use of the MD2 algorithm inside signatures by
default. (CVE-2009-2409)
An input validation flaw was found in the handling of the BMPString and
UniversalString ASN1 string types in OpenSSL's ASN1_STRING_print_ex()
function. An attacker could use this flaw to create a specially-crafted
X.509 certificate that could cause applications using the affected function
to crash when printing certificate contents. (CVE-2009-0590)
Note: The affected function is rarely used. No application shipped with Red
Hat Enterprise Linux calls this function, for example.
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.

3. Description:
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.
A ciphersuite downgrade flaw was found in the OpenSSL SSL/TLS server code.
A remote attacker could possibly use this flaw to change the ciphersuite
associated with a cached session stored on the server, if the server
enabled the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option, possibly
forcing the client to use a weaker ciphersuite after resuming the session.
(CVE-2010-4180, CVE-2008-7270)
Note: With this update, setting the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG
option has no effect and this bug workaround can no longer be enabled.
It was discovered that OpenSSL did not always check the return value of the
bn_wexpand() function. An attacker able to trigger a memory allocation
failure in that function could possibly crash an application using the
OpenSSL library and its UBSEC hardware engine support. (CVE-2009-3245)
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

3. Description:
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)
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)
A denial of service flaw was found in the RFC 3779 implementation in
OpenSSL. A remote attacker could use this flaw to make an application using
OpenSSL exit unexpectedly by providing a specially-crafted X.509
certificate that has malformed RFC 3779 extension data. (CVE-2011-4577)
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

and Transport Layer Security (TLS v1) protocols, as well as a
full-strength, general purpose cryptography library.
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.
