Juniper Networks Junos OS on SRX series devices do not verify the HTTPS server certificate before downloading anti-virus updates. This may allow a man-in-the-middle attacker to inject bogus signatures to cause service disruptions or make the device not detect certain types of attacks. Affected Junos OS releases are: 12.1X46 prior to 12.1X46-D71; 12.3X48 prior to 12.3X48-D55; 15.1X49 prior to 15.1X49-D110;Show less

When Express Path (formerly known as service offloading) is configured on Juniper Networks SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800 in high availability cluster configuration mode, certain multicast packets might cause the flowd process to crash, halting or interrupting traffic from flowing through the device and triggering RG1+ (data-plane) fail-over to the secondary node. Repeated crashes of the flowd process may constitute an extended denial of service condition. This service is not enabled by default and is only supported in high-end SRX platforms. Affected releases are Juniper Networks Junos OS 12.3X48 prior to 12.3X48-D45, 15.1X49 prior to 15.1X49-D80 on SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800.Show less

If extended statistics are enabled via 'set chassis extended-statistics', when executing any operation that fetches interface statistics, including but not limited to SNMP GET requests, the pfem process or the FPC may crash and restart. Repeated crashes of PFE processing can result in an extended denial of service condition. This issue only affects the following platforms: (1) EX2200, EX3300, XRE200 (2) MX Series routers with MPC7E/8E/9E PFEs installed, and only if 'extended-statistics' are enabled under the [edit chassis] configuration.

Any Juniper Networks SRX series device with one or more ALGs enabled may experience a flowd crash when traffic is processed by the Sun/MS-RPC ALGs. This vulnerability in the Sun/MS-RPC ALG services component of Junos OS allows an attacker to cause a repeated denial of service against the target. Repeated traffic in a cluster may cause repeated flip-flop failure operations or full failure to the flowd daemon halting traffic on all nodes. Only IPv6 traffic is affected by this issue. IPv4 traffic is unaffected. This issues is not seen with to-host traffic. This issue has no relation with HA services themselves, only the ALG service. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS 12.1X46 prior to 12.1X46-D55 on SRX; 12.1X47 prior to 12.1X47-D45 on SRX; 12.3X48 prior to 12.3X48-D32, 12.3X48-D35 on SRX; 15.1X49 prior to 15.1X49-D60 on SRX.Show less

Juniper Networks Junos OS 16.1R1, and services releases based off of 16.1R1, are vulnerable to the receipt of a crafted BGP Protocol Data Unit (PDU) sent directly to the router, which can cause the RPD routing process to crash and restart. Unlike BGP UPDATEs, which are transitive in nature, this issue can only be triggered by a packet sent directly to the IP address of the router. Repeated crashes of the rpd daemon can result in an extended denial of service condition. This issue only affects devices running Junos OS 16.1R1 and services releases based off of 16.1R1 (e.g. 16.1R1-S1, 16.1R1-S2, 16.1R1-S3). No prior versions of Junos OS are affected by this vulnerability, and this issue was resolved in Junos OS 16.2 prior to 16.2R1. No other Juniper Networks products or platforms are affected by this issue. This issue was found during internal product security testing.Show less

By flooding a Juniper Networks router running Junos OS with specially crafted IPv6 traffic, all available resources can be consumed, leading to the inability to store next hop information for legitimate traffic. In extreme cases, the crafted IPv6 traffic may result in a total resource exhaustion and kernel panic. The issue is triggered by traffic destined to the router. Transit traffic does not trigger the vulnerability. This issue only affects devices with IPv6 enabled and configured. Devices not configured to process IPv6 traffic are unaffected by this vulnerability. This issue was found during internal product security testing. Juniper SIRT is not aware of any malicious exploitation of this vulnerability.
