Titel:	Amazon Linux: Security Advisory (ALAS-2015-548)
Zusammenfassung:	The remote host is missing an update for the 'ruby21' package(s) announced via the ALAS-2015-548 advisory.
Beschreibung:	Summary: The remote host is missing an update for the 'ruby21' package(s) announced via the ALAS-2015-548 advisory. Vulnerability Insight: RubyGems provides the ability of a domain to direct clients to a separate host that is used to fetch gems and make API calls against. This mechanism is implemented via DNS, specifically a SRV record _rubygems._tcp under the original requested domain. RubyGems did not validate the hostname returned in the SRV record before sending requests to it. (CVE-2015-3900) As discussed upstream, CVE-2015-4020 is due to an incomplete fix for CVE-2015-3900, which allowed redirection to an arbitrary gem server in any security domain. Affected Software/OS: 'ruby21' package(s) on Amazon Linux. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:P/A:N
