medium Nessus Plugin ID 23706

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

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 nonexistent input.
Workaround :

There is no known workaround at this time.

Solution

All Ruby users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/ruby-1.8.5-r3'
