John Heasman discovered that the site plugin handling of the
Elasticsearch search engine was susceptible to directory traversal.

Juliane Holzt discovered that Icecast2, a streaming media server, could
dereference a NULL pointer when URL authentication is configured and the
stream_auth URL is trigged by a client without setting any credentials.
This could allow remote attackers to cause a denial of service (crash).

It was discovered that cURL, an URL transfer library, if configured to
use a proxy server with the HTTPS protocol, by default could send to the
proxy the same HTTP headers it sends to the destination server, possibly
leaking sensitive information.
