CVE-2025-52982
An Improper Resource Shutdown or Release vulnerability in the SIP ALG of Juniper Networks Junos OS on MX Series with MS-MPC allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).
When an MX Series device with an MS-MPC is configured with two or more service sets which are both processing SIP calls, a specific sequence of call events will lead to a crash and restart of the MS-MPC. This issue affects Junos OS:
- all versions before 21.2R3-S9,
- 21.4 versions from 21.4R1,
- 22.2 versions before 22.2R3-S6,
- 22.4 versions before 22.4R3-S6.
As the MS-MPC is EoL after Junos OS 22.4, later versions are not affected.
This issue does not affect MX-SPC3 or SRX Series devices.
No affected software listed.
