GLSA-202003-09 : OpenID library for Ruby: Server-Side Request Forgery

critical Nessus Plugin ID 134586

Language:

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-202003-09 (OpenID library for Ruby: Server-Side Request Forgery)

 It was discovered that OpenID library for Ruby performed discovery first, and then verification.
 Impact :

 A remote attacker could possibly change the URL used for discovery and trick the server into connecting to the URL. This server in turn could be a private server not publicly accessible.
 In addition, if the client that uses this library discloses connection errors, this in turn could disclose information from the private server to the attacker.
 Workaround :

 There is no known workaround at this time.

Solution

All ruby-openid users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-ruby/ruby-openid-2.9.2'
