Junos OS and Junos OS Evolved: RPD might crash when MPLS ping is performed on BGP LSPs

An Access of Uninitialized Pointer vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). When an MPLS ping is performed on BGP LSPs, the RPD might crash. Repeated execution of this operation will lead to a sustained DoS. This issue affects: Juniper Networks Junos OS: 15.1 versions prior to 15.1R7-S12; 19.1 versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R1-S9, 19.2R3-S5; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R2-S7, 19.4R3-S8; 20.1 versions prior to 20.1R3-S4; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R1-S1, 21.1R2; Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R2-EVO.
