Multiple buffer overflows in E-Post Mail Server 4.10 and SPA-PRO Mail @Solomon 4.00 allow remote attackers to execute arbitrary code via a long username to the (1) AUTH PLAIN or (2) AUTH LOGIN SMTP commands, which is not properly handled by (a) EPSTRS.EXE or (b) SPA-RS.EXE; (3) a long username in the APOP POP3 command, which is not properly handled by (c) EPSTPOP4S.EXE or (d) SPA-POP3S.EXE; (4) a long IMAP DELETE command, which is not properly handled by (e) EPSTIMAP4S.EXE or (f) SPA-IMAP4S.EXE.

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.
No commit or PR link among the references.
Credits
All researchersFinders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.
No credits in the CNA record.
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.
