The remote mail server is prone to a buffer overflow attack.
The remote server is running Citadel, an open source solution for
email and collaboration.
According to its version, the installation of Citadel on the remote
host uses insufficient bounds-checking in its SMTP service during
memory-copy operations when processing input to the RCPT TO command.
An unauthenticated, remote attacker may be able to leverage this issue
to cause a stack-based buffer overflow, resulting in a crash of the
affected service or even execution of arbitrary code.
Upgrade to Citadel version 7.11 or later.
