[GLSA-200611-12] Ruby: Denial of Service vulnerability

Vulnerability Assessment Summary
Ruby: Denial of Service vulnerability

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200611-12
(Ruby: Denial of Service vulnerability)

Zed Shaw, Jeremy Kemper, and Jamis Buck of the Mongrel project reported
that the CGI library shipped with Ruby is vulnerable to a remote Denial
of Service by an unauthenticated user.

Impact

The vulnerability can be exploited by sending the cgi.rb library an
HTTP request with multipart MIME encoding that contains a malformed
MIME boundary specifier beginning with "-" instead of "--". Successful
exploitation of the vulnerability causes the library to go into an
infinite loop waiting for additional non-existent input.

Workaround

There is no known workaround at this time.
