Junos OS and Junos OS Evolved: Concurrent deletion of a routing-instance and receipt of an SNMP request cause an RPD crash

A Use After Free vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an authenticated, network-based attacker to cause a Denial of Service (DoS).On all Junos OS and Junos Evolved platforms, if a routing-instance deactivation is triggered, and at the same time a specific SNMP request is received, a segmentation fault occurs which causes rpd to crash and restart.




This issue affects:

   Junos OS:



  *  All versions before 21.2R3-S8, 
  *  21.4 versions before 21.4R3-S5,
  *  22.2 versions before 22.2R3-S3,
  *  22.3 versions before 22.3R3-S2,
  *  22.4 versions before 22.4R3,
  *  23.2 versions before 23.2R2.




   Junos OS Evolved:



  *  All versions before 21.2R3-S8-EVO,
  *  21.4-EVO versions before 21.4R3-S5-EVO,
  *  22.2-EVO versions before 22.2R3-S3-EVO, 
  *  22.3-EVO versions before 22.3R3-S2-EVO,
  *  22.4-EVO versions before 22.4R3-EVO,
  *  23.2-EVO versions before 23.2R2-EVO.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
