The remote host is vulnerable to a buffer overflow.
The remote host is running ClamAV, an open-source antivirus solution for Unix-like systems. This version of ClamAV is reported vulnerable to a flaw where the parsing of a malicious file will cause the clamav process to execute arbitrary code. An attacker exploiting this flaw would only need to be able to craft and send a malformed email to a ClamAV server. Successful exploitation results in the server executing arbitrary code or crashing.
Upgrade to version 0.87.1 or higher.
