Rj415680 Patched -

The patching mechanism depends on the package manager:

RHEL/CentOS/Rocky/Alma:

rpm -qa | grep rj415680

Debian/Ubuntu:

dpkg -l | grep rj415680

Containerized environments (Docker/Kubernetes): rj415680 patched

docker exec <container_id> apt list --installed | grep rj415680

To avoid scrambling when the next RJ415680-equivalent arrives:

Post-patch, session tokens now expire strictly after 15 minutes of inactivity—down from a lax 60-minute window. Applications with long-running background tasks may encounter token renewal errors.

An attacker exploiting the unpatched version could craft a maliciously formatted request to replay a previously valid session token, effectively impersonating an authenticated user—including administrative accounts. This would allow data exfiltration, lateral movement within a network, and potential ransomware deployment. The patching mechanism depends on the package manager:

The vendor silently notified enterprise customers in January, with a public advisory following two weeks later. That advisory was accompanied by the release of RJ415680.

While vendors sometimes obfuscate exact code changes, security bulletins indicate that RJ415680 patches the following components:

| Component | Role | Fix Type | |-----------|------|-----------| | ntoskrnl.exe | Windows kernel | Memory management fix | | rpcrt4.dll | Remote Procedure Call runtime | Handle leak resolution | | srv2.sys | Server message block (SMB) 2.0 driver | Cancellation of orphaned requests | Debian/Ubuntu: dpkg -l | grep rj415680

Additionally, if RJ415680 is part of an ERP context (e.g., Dynamics NAV or Business Central), it also patches:

In that scenario, the patch corrected a deadlock condition when multiple users executed the same report concurrently.

If your system is unpatched, follow these steps. Always back up configuration files and create a system restore point before proceeding.
