This one https://github.com/trusteddomainproject/OpenDMARC/pull/45 caught my attention. Quote: "Fix a few potential crashes Fix missing from_domain check for store_dkim Add checks for longer than buffer while parsing record" This seems to add and fix a few length checks for buffers, i.e. fixing buffer overflows. I haven't analyzed it in detail. -- Hanno Böck https://hboeck.de/ mail/jabber: hanno@...eck.de GPG: FE73757FA60E4E21B937579FA5880072BBB51E42
