Vulnerability Assessment Details
Ruby on Rails: Several vulnerabilities
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200608-20
(Ruby on Rails: Several vulnerabilities)
The Ruby on Rails developers have corrected some weaknesses in
action_controller/, relative to the handling of the user input and the
LOAD_PATH variable. A remote attacker could inject arbitrary entries
into the LOAD_PATH variable and alter the main Ruby on Rails process.
The security hole has only been partly solved in version 1.1.5. Version
1.1.6 now fully corrects it.
A remote attacker that would exploit these weaknesses might cause a
Denial of Service of the web framework and maybe inject arbitrary Ruby
There is no known workaround at this time.
All Ruby on Rails users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/rails-1.1.6"
Network Security Threat Level: High
