Summary
A Use After Free vulnerability in the routing protocol daemon of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause Denial of Service (DoS). In a rib sharding scenario the rpd process will crash shortly after specific CLI command is issued. This issue is more likely to occur in a scenario with high route scale (>1M routes). This issue affects: Juniper Networks Junos OS • 20.2 version 20.2R3-S5 and later versions prior to 20.2R3-S6; • 20.3 version 20.3R3-S2 and later versions prior to 20.3R3-S5; • 20.4 version 20.4R3-S1 and later versions prior to 20.4R3-S4 • 21.1 version 21.1R3 and later versions prior to 21.1R3-S3; • 21.2 version 21.2R1-S2, 21.2R2-S1 and later versions prior to 21.2R3-S2; • 21.3 version 21.3R2 and later versions prior to 21.3R3; • 21.4 versions prior to 21.4R2-S1, 21.4R3; • 22.1 versions prior to 22.1R2.
