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).
