SpamAssassin spamd --vpopmail/-P command execution
| spamassassin-spamd-command-execution (27008) |  High Risk |

SpamAssassin could allow a remote attacker to execute arbitrary commands on the system. If spamd is executed with the --vpopmail (-v) and --paranoid (-P) switches, a remote attacker could send a message using a specially-crafted virtual pop username to execute arbitrary commands on the affected system with the privileges of the spamd daemon.
