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]");
