Vulnerability Assessment Details

[GLSA-200612-21] 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-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.
