Title
Junos OS: vMX and MX150: Specific packets might cause a memory leak and eventually an FPC reboot
Summary
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.
