CVE-2012-2110

Status Candidate

Overview

The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1 before 1.0.1a does not properly interpret integer data, which allows remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key.

FreeBSD Security Advisory - OpenSSL
Posted May 3, 2012
Site security.freebsd.org

FreeBSD 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.

Debian Linux Security Advisory 2454-1 - Multiple vulnerabilities have been found in OpenSSL. 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). It was discovered that a NULL pointer could be dereferenced when parsing certain S/MIME messages, leading to denial of service. 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.

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1424-1 - It was discovered that OpenSSL could be made to dereference a NULL pointer when processing S/MIME messages. A remote attacker could use this to cause a denial of service. These issues did not affect Ubuntu 8.04 LTS. Tavis Ormandy discovered that OpenSSL did not properly perform bounds checking when processing DER data via BIO or FILE functions. A remote attacker could trigger this flaw in services that used SSL to cause a denial of service or possibly execute arbitrary code with application privileges. Various other issues were also addressed.

OpenSSL Memory Corruption
Posted Apr 19, 2012
Authored by Tavis Ormandy

OpenSSL versions up to and including 1.0.1 are affected by a memory corruption vulnerability. asn1_d2i_read_bio in OpenSSL contains multiple integer errors that can cause memory corruption when parsing encoded ASN.1 data. This error can be exploited on systems that parse untrusted data, such as X.509 certificates or RSA public keys.
