JDPI incorrectly classifie...

CVE-2022-22178 Junos OS: MX and SRX series: Flowd core observed if the SIP ALG is enabled and a specific Session Initiation Protocol (SIP) packet is received

A Stack-based Buffer Overflow vulnerability in the flow processing daemon flowd of Juniper Networks Junos OS on MX Series and SRX series allows an unauthenticated networked attacker to cause a flowd crash and thereby a Denial of Service DoS. Continued receipt of these specific packets will cause ...

CVE-2022-22175 Junos OS: MX Series and SRX Series: The flowd daemon will crash if the SIP ALG is enabled and specific SIP messages are processed

An Improper Locking vulnerability in the SIP ALG of Juniper Networks Junos OS on MX Series and SRX Series allows an unauthenticated networked attacker to cause a flowprocessing daemon flowd crash and thereby a Denial of Service DoS. Continued receipt of these specific packets will cause a sustain...

CVE-2022-22175

The CVE covers an Improper Locking vulnerability in the SIP ALG of Juniper Junos OS on MX Series and SRX Series, causing the flowd daemon to crash and trigger DoS when specific SIP traffic is processed with SIP ALG enabled. Affected versions include Junos OS: 20.4 (before 20.4R3‑S1), 21.1 (before...

CVE-2022-22167 Junos OS: SRX Series: If no-syn-check is enabled, traffic classified as UNKNOWN gets permitted by pre-id-default-policy

A traffic classification vulnerability in Juniper Networks Junos OS on the SRX Series Services Gateways may allow an attacker to bypass Juniper Deep Packet Inspection JDPI rules and access unauthorized networks or resources, when 'no-syn-check' is enabled on the device. While JDPI correctly...

CVE-2022-22167

CVE-2022-22167 describes a traffic classification vulnerability in Juniper Networks Junos OS on SRX Series gateways where enabling no-syn-check causes JDPI to misclassify certain TCP flows, leading the policy to permit traffic that should be denied via the pre-id-default-policy. Affected are SRX ...

CVE-2022-22157

Summary: CVE-2022-22157 describes a traffic-classification vulnerability in Juniper Networks Junos OS on SRX Series gateways where the Deep Packet Inspection (JDPI) rules can be bypassed when the device is configured with no-syn-check. The issue stems from JDPI misclassifying out-of-state asymmet...
