An attacker could possibly use this issue to open libraries with tainted names. This issue only applied to Ubuntu 14.04 LTS. (CVE-2009-5147)</p> <p>Tony Arcieri, Jeffrey Walton, and Steffan Ullrich discovered that the Ruby OpenSSL extension incorrectly handled hostname wildcard matching. This issue only applied to Ubuntu 14.04 LTS. (CVE-2015-1855)</p> <p>Christian Hofstaedtler discovered that Ruby Fiddle::Handle incorrectly handled certain crafted strings. An attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 14.04 LTS.

This issue only affected Ubuntu 14.04 LTS. (CVE-2016-2337)</p> <p>It was discovered that Ruby Fiddle::Function.new incorrectly handled certain arguments. An attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2016-2339)</p> <p>It was discovered that Ruby incorrectly handled the initialization vector (IV) in GCM mode. An attacker could possibly use this issue to bypass encryption.
