Description

An Improper Validation of Specified Type of Input vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated adjacent attacker to trigger a Missing Release of Memory after Effective Lifetime vulnerability. Continued exploitation of this vulnerability will eventually lead to an FPC reboot and thereby a Denial of Service (DoS). This issue affects: Juniper Networks Junos OS on vMX and MX150: All versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S5, 19.4R3-S6; 20.1 versions prior to 20.1R3-S2; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2-S1, 21.1R3; 21.2 versions prior to 21.2R1-S1, 21.2R2; 21.3 versions prior to 21.3R1-S1, 21.3R2.
