Ruby: Denial of Service vulnerability Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200612-21 (Ruby: Denial of Service vulnerability) The read_multipart function of the CGI library shipped with Ruby (cgi.rb) does not properly check boundaries in MIME multipart content. This is a different issue than GLSA 200611-12. Impact The vulnerability can be exploited by sending the cgi.rb library a crafted HTTP request with multipart MIME encoding that contains a malformed MIME boundary specifier. Successful exploitation of the vulnerability causes the library to go into an infinite loop. Workaround There is no known workaround at this time.
