RSA BSAFE Micro Edition Suite versions prior to 4.4 (in 4.0.x, 4.1.x, 4.2.x and 4.3.x) are vulnerable to a Heap-based Buffer Overflow vulner
RSA BSAFE Micro Edition Suite versions prior to 4.4 (in 4.0.x, 4.1.x, 4.2.x and 4.3.x) are vulnerable to a Heap-based Buffer Overflow vulnerability when parsing ECDSA signature. A malicious user with adjacent network access could potentially exploit this vulnerability to cause a crash in the library of the affected system.

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.
