Summary

Amavis before 2.12.3 and 2.13.x before 2.13.1, in part because of its use of MIME-tools, has an Interpretation Conflict (relative to some mail user agents) when there are multiple boundary parameters in a MIME email message. Consequently, there can be an incorrect check for banned files or malware.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
