Vulnerability Title
Junos OS and Junos OS Evolved: Receipt of malformed BGP path attributes leads to a memory leak
Source: CVE Program / CVE List V5
Vulnerability Description
A Missing Release of Memory after Effective Lifetime vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This memory is not properly freed in all circumstances, leading to a Denial of Service (DoS). Consumed memory can be freed by manually restarting Routing Protocol Daemon (rpd). Memory utilization could be monitored by:  user@host> show system memory or show system monitor memory status This issue affects: Junos OS:  * All versions before 21.2R3-S8,  * from 21.4 before 21.4R3-S8, * from 22.2 before 22.2R3-S4,  * from 22.3 before 22.3R3-S3,  * from 22.4 before 22.4R3-S3, * from 23.2 before 23.2R2-S1,  * from 23.4 before 23.4R1-S2, 23.4R2.
