In versions 0.9.7 and prior, 0.10.0 through 0.10.6, and 0.11.0 through
0.11.2, there is a vulnerability that leads to possible remote code
execution in the mailing action mail-whois. Command `mail` from mailutils
package used in mail actions like `mail-whois` can execute command if
unescaped sequences (`\n~`) are available in 'foreign' input (for
instance in whois output). To exploit the vulnerability, an attacker would
need to insert malicious characters into the response sent by the whois
server, either via a MITM attack or by taking over a whois server.
