Multiple unspecified vulnerabilities in WorldClient in Alt-N MDaemon before 10.02 have unknown impact and attack vectors, probably related to cross-site scripting (XSS) and WorldClient DLL 10.0.1, a different vulnerability than CVE-2008-6893.

Multiple unspecified vulnerabilities in MDaemon and WorldClient in Alt-N Technologies MDaemon before 9.50 allow attackers to cause a denial of service (memory consumption) via unspecified vectors resulting in memory leaks.

Multiple heap-based buffer overflows in the POP3 server in Alt-N Technologies MDaemon before 9.0.6 allow remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via long strings that contain '@' characters in the (1) USER and (2) APOP commands.

Buffer overflow in Alt-N MDaemon, possibly 9.0.1 and earlier, allows remote attackers to execute arbitrary code via a long A0001 argument that begins with a '"' (double quote).

Alt-N Technologies MDaemon 5.0.5.0 and earlier creates a default MDaemon mail account with a password of MServer, which could allow remote attackers to send anonymous email.

Buffer overflow in WorldClient.cgi in WorldClient in Alt-N Technologies MDaemon 5.0.5.0 and earlier allows local users to execute arbitrary code via a long folder name (NewFolder parameter).
