CVE-2009-0789

Status Candidate

Overview

OpenSSL before 0.9.8k on WIN64 and certain other platforms does not properly handle a malformed ASN.1 structure, which allows remote attackers to cause a denial of service (invalid memory access and application crash) by placing this structure in the public key of a certificate, as demonstrated by an RSA public key.

OpenSSL Toolkit
Posted Mar 30, 2009
Site openssl.org

OpenSSL is a robust, fully featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols with full-strength cryptography world-wide.

Changes: Three security flaws of moderate severity were fixed - Printing the contents of an ASN1 certificate with an illegal encoded length could cause an application crash. CMS verification could cause an invalid set of signed attributes to appear valid. A malformed ASN1 structure could cause invalid memory access. Further minor modifications were made.
