tag_insight = "FreeBSD includes software from the OpenSSL Project.  The OpenSSL Project is
a collaborative effort to develop a robust, commercial-grade, full-featured,
and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols as well as a full-strength
general purpose cryptography library.

Several problems have been found in OpenSSL:

1. During the parsing of certain invalid ASN1 structures an error condition
is mishandled, possibly resulting in an infinite loop.  [CVE-2006-2937]

2. A buffer overflow exists in the SSL_get_shared_ciphers function.
[CVE-2006-3738]

3. A NULL pointer may be dereferenced in the SSL version 2 client code.
[CVE-2006-4343]

In addition, many applications using OpenSSL do not perform any validation
of the lengths of public keys being used. [CVE-2006-2940]";
