OSVDB

Short for Open Source Vulnerability Database, OSVDB is an independent community-driven open source database. The project promotes greater, open collaboration between companies and individuals, eliminates redundant works, and reduce expenses inherent with the development and maintenance of in-house vulnerability databases. The project was started in August 2002 at the Blackhat and DEF CON Conferences by industry notables. The database officially launched for public use on March 31, 2004.
