Detailsinfo

A vulnerability was found in Juniper Junos on QFX/PTX (Router Operating System) (the affected version unknown). It has been declared as problematic. Affected by this vulnerability is an unknown part of the component J-Flow Sampling. The manipulation as part of a Malformed Packet leads to a data processing vulnerability. The CWE definition for the vulnerability is CWE-19. As an impact it is known to affect availability. The summary by CVE is:

On QFX and PTX Series, receipt of a malformed packet for J-Flow sampling might crash the FPC (Flexible PIC Concentrator) process which causes all interfaces to go down. By continuously sending the offending packet, an attacker can repeatedly crash the FPC process causing a sustained Denial of Service (DoS). This issue affects both IPv4 and IPv6 packet processing. Affected releases are Juniper Networks Junos OS on QFX and PTX Series: 17.4 versions prior to 17.4R2-S1, 17.4R3; 18.1 versions prior to 18.1R3-S1; 18.2 versions prior to 18.2R1-S3, 18.2R2; 17.2X75 versions prior to 17.2X75-D91, 17.2X75-D100.
