An Untrusted Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, authenticated attacker with low privileges to cause a Denial-of-Service (DoS).
When the command show route < ( receive-protocol | advertising-protocol ) bgp > detail is executed, and at least one of the routes in the intended output has specific attributes, this will cause an rpd crash and restart. show route … extensive is not affected.
This issue affects:
Junos OS:
- all versions before 22.4R3-S8,
- 23.2 versions before 23.2R2-S5,
- 23.4 versions before 23.4R2-S5,
- 24.2 versions before 24.2R2-S2,
- 24.4 versions before 24.4R2;
Junos OS Evolved:
- all versions before 22.4R3-S8-EVO,
- 23.2 versions before 23.2R2-S5-EVO,
- 23.4 versions before 23.4R2-S6-EVO,
- 24.2 versions before 24.2R2-S2-EVO,
- 24.4 versions before 24.4R2-EVO.
Weakness
The product obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer.

Extended Description
An attacker can supply a pointer for memory locations that the product is not expecting. If the pointer is dereferenced for a write operation, the attack might allow modification of critical state variables, cause a crash, or execute code. If the dereferencing operation is for a read, then the attack might allow reading of sensitive data, cause a crash, or set a variable to an unexpected value (since the value will be read from an unexpected memory location). There are several variants of this weakness, including but not necessarily limited to:
