DESCRIPTION:
A vulnerability has been reported in Sun Solaris, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an unspecified error in the
OpenSSL PKCS#11 engine. This can be exploited to corrupt the SSL
session cache and cause the "RSA_sign" and "RSA_verify" cryptographic
operations to fail.

NOTE: If the engine is used by the Apache webserver, the
vulnerability will result in SSL connections being dropped in the
handshake phase.

The vulnerability is reported in Solaris 10 for both the SPARC and
x86 platforms.
