A interpretation conflict in Fortinet IPS Engine versions 7.321, 7.166 and 6.158 allows attacker to evade IPS features via crafted TCP packets.

Multiple padding oracle vulnerabilities (Zombie POODLE, GOLDENDOODLE, OpenSSL 0-length) in the CBC padding implementation of FortiOS IPS engine version 5.000 to 5.006, 4.000 to 4.036, 4.200 to 4.219, 3.547 and below, when configured with SSL Deep Inspection policies and with the IPS sensor enabled, may allow an attacker to decipher TLS connections going through the FortiGate via monitoring the traffic in a Man-in-the-middle position.
