Summary

Insight

Insight

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. It was discovered that the Datagram Transport Layer Security (DTLS) protocol implementation in OpenSSL leaked timing information when performing certain operations. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a DTLS server as a padding oracle. (CVE-2011-4108) An information leak flaw was found in the SSL 3.0 protocol implementation in OpenSSL. Incorrect initialization of SSL record padding bytes could cause an SSL client or server to send a limited amount of possibly sensitive data to its SSL peer via the encrypted connection. (CVE-2011-4576) A denial of service flaw was found in the RFC 3779 implementation in OpenSSL. A remote attacker could use this flaw to make an application using OpenSSL exit unexpectedly by providing a specially-crafted X.509 certificate that has malformed RFC 3779 extension data. (CVE-2011-4577) It was discovered that OpenSSL did not limit the number of TLS/SSL handshake restarts required to support Server Gated Cryptography. A remote attacker could use this flaw to make a TLS/SSL server using OpenSSL consume an excessive amount of CPU by continuously restarting the handshake. (CVE-2011-4619) All OpenSSL users should upgrade to these updated packages, which contain backported patches to resolve these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.
