Red Hat Security Advisory 2012-1308-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. Multiple numeric conversion errors, leading to a buffer overflow, were found in the way OpenSSL parsed ASN.1 data from BIO inputs. Specially-crafted DER encoded data read from a file or other BIO input could cause an application using the OpenSSL library to crash or, potentially, execute arbitrary code.

ab37b6926b046653acdeeef66e7c85baHP Security Bulletin HPSBOV02793 SSRT100891 - Potential security vulnerabilities have been identified with HP OpenVMS running SSL. The vulnerabilities could be remotely exploited to cause a Denial of Service (DoS) or to gain unauthorized access. Revision 1 of this advisory.
81afd5381e1f8df30bc1eda96940a682d60e52c9185ef5115fed35b8f301ab7cFreeBSD Security Advisory - 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. OpenSSL support for handshake restarts for server gated cryptography (SGC) can be used in a denial-of-service attack. Various other OpenSSL issues have also been addressed.

A heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host or, possibly, escalate their privileges on the host.

This could allow an attacker to determine private keys via a timing attack. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. Adam Langley discovered that the ephemeral Elliptic Curve Diffie-Hellman (ECDH) functionality in OpenSSL did not ensure thread safety while processing handshake messages from clients. This could allow a remote attacker to cause a denial of service via out-of-order messages that violate the TLS protocol. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. Various other issues were also addressed.

b2265e92d8b81cb40b2add6a630d861f1b28f98b30119e91fd07549aa77efff1Red Hat Security Advisory 2012-0060-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. It was discovered that the Datagram Transport Layer Security 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. 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.

Double free vulnerability in OpenSSL 0.9.8 before 0.9.8s, when X509_V_FLAG_POLICY_CHECK is enabled, allows remote attackers to have an unspecified impact by triggering failure of a policy check. The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize data structures for block cipher padding, which might allow remote attackers to obtain sensitive information by decrypting the padding data sent by an SSL peer. The Server Gated Cryptography implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service via unspecified vectors. The GOST ENGINE in OpenSSL before 1.0.0f does not properly handle invalid parameters for the GOST block cipher, which allows remote attackers to cause a denial of service via crafted data from a TLS client. The updated packages have been patched to correct these issues.

The DTLS implementation performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack. A double free vulnerability when X509_V_FLAG_POLICY_CHECK is enabled, allows remote attackers to cause applications crashes and potentially allow execution of arbitrary code by triggering failure of a policy check. On 32-bit systems, the operations on NIST elliptic curves P-256 and P-384 are not correctly implemented, potentially leaking the private ECC key of a TLS server. (Regular RSA-based keys are not affected by this vulnerability.) Various other issues were also addressed.

Their attack exploits timing differences arising during decryption processing. Other issues were also addressed.
