A flaw was found in OpenSSL in how it processes key and initialization vector (IV) lengths. This issue can lead to potential truncation or overruns during the initialization of some symmetric ciphers. A truncation in the IV can result in non-uniqueness, which could result in loss of confidentiality for some cipher modes. Both truncations and overruns of the key and the IV will produce incorrect results and could, in some cases, trigger a memory exception.
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
