Product: Solaris 10 Operating System

A security vulnerability in the OpenSSL PKCS#11 engine as shipped with Solaris 10 may affect applications which make use of this engine. The exact impact will vary depending on the application. This vulnerabiltiy may allow a local or remote unprivileged user to cause certain cryptographic operations within the application to fail (namely RSA_sign and RSA_verify), which is a type of Denial of Service (DoS).

For example, if the OpenSSL PKCS#11 engine is used for SSL processing (for example, in the Apache webserver) it will result in SSL connections being dropped in the SSL handshake phase, thereby causing a Denial Of Service (DoS) due to a corrupted session cache.

Title: A Security Vulnerability in the OpenSSL PKCS#11 Engine May Result in Denial of Service (DoS) Due to a Corrupted Session Cache
Description: The PK11_SESSION cache in the OpenSSL PKCS#11 engine in Sun Solaris 10 does not maintain reference counts for operations with asymmetric keys, which allows context-dependent attackers to cause a denial of service (failed cryptographic operations) via unspecified vectors, related to the (1) RSA_sign and (2) RSA_verify functions.
