Summaries and Symptoms

Service console package for OpenSSL is updated to version openssl097a-0.9.7a-9.el5_2.1. The functions inside OpenSSL incorrectly check the result after calling the EVP_VerifyFinal function, which allows a malformed signature to be accepted as valid rather than as an error. This issue affects the signature checks on DSA and ECDSA keys used with SSL/TLS.

The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2008-5077 to this issue.

Deployment Considerations

None beyond the required patch bundles and reboot information listed in the table above.
