Title
Junos OS and Junos OS Evolved: If malformed IPv6 router advertisements are received, memory corruption will occur which causes an rpd crash
Summary
An Improper Input Validation vulnerability in the kernel of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). If the receipt of router advertisements is enabled on an interface and a specifically malformed RA packet is received, memory corruption will happen which leads to an rpd crash. This issue affects: Juniper Networks Junos OS 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S3; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R2. Juniper Networks Junos OS Evolved 20.3-EVO version 20.3R1-EVO and later versions; 20.4-EVO versions prior to 20.4R3-S6-EVO; 21.3-EVO versions prior to 21.3R3-EVO; 21.4-EVO versions prior to 21.4R2-EVO; 22.1-EVO versions prior to 22.1R2-EVO.
