  • CWE-755 - Improper Handling of Exceptional Conditions
Summary
An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a logically adjacent downstream RSVP neighbor to cause kernel memory exhaustion, leading to a kernel crash, resulting in a Denial of Service (DoS). The kernel memory leak and eventual crash will be seen when the downstream RSVP neighbor has a persistent error which will not be corrected. System kernel memory can be monitored through the use of the 'show system kernel memory' command as shown below: user@router> show system kernel memory   Real memory total/reserved: 4130268/ 133344 Kbytes kmem map free: 18014398509110220 Kbytes This issue affects: Junos OS: * All versions before 20.4R3-S9, * All versions of 21.2, * from 21.4 before 21.4R3-S5, * from 22.1 before 22.1R3-S5, * from 22.2 before 22.2R3-S3, * from 22.3 before 22.3R3-S2, * from 22.4 before 22.4R3, * from 23.2 before 23.2R2; Junos OS Evolved: * All versions before 21.4R3-S5-EVO, * from 22.1-EVO before 22.1R3-S5-EVO, * from 22.2-EVO before 22.2R3-S3-EVO, * from 22.3-EVO before 22.3R3-S2-EVO, * from 22.4-EVO before 22.4R3-EVO, * from 23.2-EVO before 23.2R2-EVO.
