TITLE

Juniper Networks Junos OS Input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-003414

DESCRIPTION

When BGP tracing is enabled an incoming BGP message may cause the Junos OS routing protocol daemon (rpd) process to crash and restart. While rpd restarts after a crash, repeated crashes can result in an extended DoS condition. Affected releases are Juniper Networks Junos OS: 16.1 versions prior to 16.1R7-S4, 16.1R7-S5; 16.2 versions prior to 16.2R2-S9, 16.2R3; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R3-S1; 17.3 versions prior to 17.3R3-S3, 17.3R3-S4, 17.3R4; 17.4 versions prior to 17.4R1-S7, 17.4R2-S3, 17.4R2-S4, 17.4R3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S4, 18.1R4; 18.2 versions prior to 18.2R2-S2, 18.2R2-S3, 18.2R3; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3, 18.3R2; 18.4 versions prior to 18.4R1-S2, 18.4R2. This issue does not affect Junos releases prior to 16.1R1. Juniper Networks Junos OS Contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Juniper Junos is prone to a remote denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition, effectively denying service to legitimate users. Juniper Networks Junos OS is a set of network operating system of Juniper Networks (Juniper Networks) dedicated to the company's hardware equipment. The operating system provides a secure programming interface and Junos SDK. A security vulnerability exists in Juniper Networks Junos OS. The following versions are affected: Juniper Networks Junos OS Release 16.1, Release 16.2, Release 17.1, Release 17.2, Release 17.3, Release 17.4, Release 18.1, Release 18.2, Release 18.2X75, Release 18.3, Release 18.4
