+    ### Summary
+    An authentication bypass vulnerability was found in ruby-saml due to a parser differential.
+    ReXML and Nokogiri parse XML differently, the parsers can generate entirely
+    different document structures from the same XML input. That allows an attacker
+    to be able to execute a Signature Wrapping attack.
+
+    ### Impact
+    This issue may lead to authentication bypass.

+  description: |-
+    ### Summary
+    ruby-saml is susceptible to remote Denial of Service (DoS) with compressed SAML responses.
+
+    Ruby-saml uses zlib to decompress SAML responses in case they're compressed.
+    It is possible to bypass the message size check with a compressed assertion
+    since the message size is checked before inflation and not after.
+
+    ### Impact
+    This issue may lead to remote Denial of Service (DoS).
