SpamAssassin Milter Plugin expand (-x) flag command execution
|spamassassin-expand-command-execution (56732)||High Risk|
The SpamAssassin Milter Plugin could allow a remote attacker to execute arbitrary commands on the system, caused by the improper validation of input by the mlfi_envrcpt function prior to being used in a popen() function call. If invoked with the expand (-x) flag, a remote attacker could send a specially crafted RCPT TO value to inject and execute arbitrary shell commands on the system with elevated privileges.
Apply the appropriate patch for your system. See References.
