OpenSSL fails to clear the bytes used as block cipher padding in SSL
3.0 records when operating as a client or a server that accept SSL 3.0
handshakes. As a result, in each record, up to 15 bytes of
uninitialized memory may be sent, encrypted, to the SSL peer. This
could include sensitive contents of previously freed memory.
[CVE-2011-4576]

OpenSSL support for handshake restarts for server gated cryptography
(SGC) can be used in a denial-of-service attack. [CVE-2011-4619]

If an application uses OpenSSL's certificate policy checking when
verifying X509 certificates, by enabling the X509_V_FLAG_POLICY_CHECK
flag, a policy check failure can lead to a double-free.
[CVE-2011-4109]

A weakness in the OpenSSL PKCS #7 code can be exploited using
Bleichenbacher's attack on PKCS #1 v1.5 RSA padding also known as the
million message attack (MMA). [CVE-2012-0884]

The asn1_d2i_read_bio() function, used by the d2i_*_bio and d2i_*_fp
functions, in OpenSSL contains multiple integer errors that can cause
memory corruption when parsing encoded ASN.1 data. This error can
occur on systems that parse untrusted ASN.1 data, such as X.509
certificates or RSA public keys. [CVE-2012-2110]"

"Updated openssl packages that fix one security issue and one bug are
now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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.

An integer underflow flaw, leading to a buffer over-read, was found in
the way OpenSSL handled DTLS (Datagram Transport Layer Security)
application data record lengths when using a block cipher in CBC
(cipher-block chaining) mode. A malicious DTLS client or server could
use this flaw to crash its DTLS connection peer. (CVE-2012-2333)

Red Hat would like to thank the OpenSSL project for reporting this
issue. Upstream acknowledges Codenomicon as the original reporter.

On Red Hat Enterprise Linux 6, this update also fixes an uninitialized
variable use bug, introduced by the fix for CVE-2012-0884 (released
via RHSA-2012:0426). This bug could possibly cause an attempt to
create an encrypted message in the CMS (Cryptographic Message Syntax)
format to fail.

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

"Multiple vulnerabilities have been found in OpenSSL. The Common
Vulnerabilities and Exposures project identifies the following issues
:

  - CVE-2012-0884
    Ivan Nestlerode discovered a weakness in the CMS and
    PKCS #7 implementations that could allow an attacker to
    decrypt data via a Million Message Attack (MMA).

  - CVE-2012-1165
    It was discovered that a NULL pointer could be
    dereferenced when parsing certain S/MIME messages,
    leading to denial of service.

  - CVE-2012-2110
    Tavis Ormandy, Google Security Team, discovered a
    vulnerability in the way DER-encoded ASN.1 data is
    parsed that can result in a heap overflow.

Additionally, the fix for CVE-2011-4619 has been updated to address an
issue with SGC handshakes.

Tomas Hoger, Red Hat, discovered that the fix for CVE-2012-2110 for
the 0.9.8 series of OpenSSL was incomplete. It has been assigned the
CVE-2012-2131 identifier."

"Updated openssl packages that fix one security issue and one bug are

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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.

An integer underflow flaw, leading to a buffer over-read, was found in
the way OpenSSL handled DTLS (Datagram Transport Layer Security)
application data record lengths when using a block cipher in CBC
(cipher-block chaining) mode. A malicious DTLS client or server could
use this flaw to crash its DTLS connection peer. (CVE-2012-2333)

Red Hat would like to thank the OpenSSL project for reporting this
issue. Upstream acknowledges Codenomicon as the original reporter.

On Red Hat Enterprise Linux 6, this update also fixes an uninitialized
variable use bug, introduced by the fix for CVE-2012-0884 (released
via RHSA-2012:0426). This bug could possibly cause an attempt to
create an encrypted message in the CMS (Cryptographic Message Syntax)
format to fail.

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