CVE-2022-22180

CVE-2022-22180 affects Junos OS on EX2300/EX2300-MP/EX3400 series. Vulnerability arises from an improper check for unusual or exceptional conditions during processing of specific IPv6 packets, leading to DMA memory exhaustion and a Denial of Service. Observed symptoms include fpc0 (buf alloc) fai...

CVE-2022-22179

CVE-2022-22179 affects Juniper Networks Junos OS’s DHCP daemon (jdhcpd), caused by improper validation of input index/offset, leading to jdhcpd crash and DoS when a DHCPv4 packet with specific options is processed. Affected software ranges from Junos OS 17.4R1 onward to 21.3R1-S1/S2, with various...

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-2022-22178

CVE-2022-22178 affects Juniper Networks Junos OS on MX Series and SRX Series with the flowd daemon. A stack-based buffer overflow in flowd can be triggered by a specific SIP INVITE when SIP ALG is enabled, causing the flowd process to crash and a sustained DoS, rebooting the PIC and dropping trav...

CVE-2022-22177

CVE-2022-22177 affects Juniper Networks Junos OS and Junos OS Evolved.
