Description:
Nemesis Security Audit Group has discovered a vulnerability in MDaemon, which potentially can be exploited by malicious users to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the handling of IMAP mail folder names containing format string specifiers. This can be exploited to cause the service to consume large amount of CPU resources by first creating email folders with format string specifiers in their names and then listing them.
The vulnerability has been confirmed in version 8.1.4 and also reported in version 8.1.1. Other versions may also be affected.
Solution:
Update to version 8.15.
