An Incorrect Calculation of Buffer Size vulnerability in Juniper Networks Junos OS SRX 5000 Series devices using SPC2 line cards while ALGs are enabled allows an attacker sending specific crafted packets to cause a transit traffic Denial of Service (DoS).

Continued receipt and processing of these specific packets will sustain the Denial of Service condition.

This issue affects:
Juniper Networks Junos OS SRX 5000 Series with SPC2 with ALGs enabled.

All versions earlier than 21.2R3-S7;
21.4 versions earlier than 21.4R3-S6;
22.1 versions earlier than 22.1R3-S5;
22.2 versions earlier than 22.2R3-S3;
22.3 versions earlier than 22.3R3-S2;
22.4 versions earlier than 22.4R3;
23.2 versions earlier than 23.2R2.
