**Name of the Vulnerable Software and Affected Versions** OpenSSL versions prior to 0.9.8y OpenSSL versions prior to 1.0.0j **Description** The issue affects the OpenSSL package in Gentoo Linux, potentially leading to breaches in confidentiality, integrity, and availability of protected information. It is caused by an integer underflow in OpenSSL when TLS 1.1, TLS 1.2, or DTLS is used with CBC encryption. This can allow remote attackers to cause a denial of service or possibly have other unspecified impacts via a crafted TLS packet. **Recommendations** For versions prior to 0.9.8y, update to version 0.9.8y or later. For versions prior to 1.0.0j, update to version 1.0.0j or later.

**Name of the Vulnerable Software and Affected Versions** OpenSSL versions prior to 1.0.0j OpenSSL versions prior to 0.9.8y **Description** The issue affects the implementation of Cryptographic Message Syntax (CMS) and PKCS #7 in OpenSSL, where certain oracle behavior is not properly restricted. This makes it easier for attackers to decrypt data via a Million Message Attack (MMA) adaptive chosen ciphertext attack, potentially leading to a breach of confidentiality, integrity, and availability of protected information. Exploitation can be done remotely. **Recommendations** For versions prior to 1.0.0j, update to version 1.0.0j or later. For versions prior to 0.9.8y, update to version 0.9.8y or later.
