'yvc' is a software package vulnerability checker. 'yvc' compares the given package name against the list of known vulnerabilities and reports any security issues. This output contains the name and version of the package, the type of vulnerability, and a URL for further information for each vulnerable package. 'yvc' was conceptually based on NetBSD's audit-packages program (see http://www.netbsd.org/support/security/#check-pkgsrc) and was written by Jan Schaumann <jschauma@yahoo-inc.com> in 2008 while working at Yahoo! Inc. Yahoo! open sourced this tool in the hopes that it will be useful to other people -- unless otherwise noted, all files are released under the terms of a 3-clause BSD license as noted in the file LICENSE. The 'y' in yvc can stand for a number of things. Make up your own. 'yvc' has a rudimentary website at: http://www.netmeister.org/apps/yvc/
