Description:
Two vulnerabilities have been reported in Ruby, which can be exploited by malicious people to bypass certain security restrictions, and to cause a DoS (Denial of Service).
1) An error exists in "eval.c" when enforcing safe-level protections. This can be exploited to execute certain insecure methods.
The vulnerability has been reported in the following versions:
* Ruby version 1.6.8 and prior (old release).
* Ruby version 1.8.2 and prior (stable).
* Ruby version 1.9.0 2005-09-01 and prior (development).
2) An error within the XMLRPC::Server and WEBrick::HTTPServer classes can cause a server that is written using the classes to stop accept connections via a specially-crafted request that causes the server block on a socket operation.
The vulnerability has been reported in the following versions:
* Ruby version 1.8.2 and prior (stable).
* Ruby version 1.9.0 prior to 2005-07-10 (development).
