(SpamAssassin: Execution of arbitrary code)

    When spamd is run with both the '--vpopmail' (-v) and
    '--paranoid' (-P) options, it is vulnerable to an unspecified issue.
  
Impact :

    With certain configuration options, a local or even remote
    attacker could execute arbitrary code with the rights of the user
    running spamd, which is root by default, by sending a crafted message
    to the spamd daemon. Furthermore, the attack can be remotely
    performed if the '--allowed-ips' (-A) option is present and specifies
    non-local adresses. Note that Gentoo Linux is not vulnerable in the
    default configuration.
  
Workaround :

    Don't use both the '--paranoid' (-P) and the '--vpopmail' (-v)
    options."
