An issue was discovered in EMC Data Domain DD OS 5.7 family, versions prior to 5.7.5.6; EMC Data Domain DD OS 6.0 family, versions prior to 6.0.2.9; EMC Data Domain DD OS 6.1 family, versions prior to 6.1.0.21; EMC Data Domain Virtual Edition 2.0 family, all versions; EMC Data Domain Virtual Edition 3.0 family, versions prior to 3.0 SP2 Update 1; and EMC Data Domain Virtual Edition 3.1 family, versions prior to 3.1 Update 2. EMC Data Domain DD OS contains a memory overflow vulnerability in SMBv1 which may potentially be exploited by an unauthenticated remote attacker. An attacker may completely shut down both the SMB service and active directory authentication. This may also allow remote code injection and execution.

Remediation
Which version to upgrade to
Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
