CVE-2017-7414

In Horde_Crypt before 2.7.6, as used in Horde Groupware Webmail Edition 5.x
through 5.2.17, OS Command Injection can occur if the user has PGP features
enabled in the user’s preferences, and has enabled the “Should PGP signed
messages be automatically verified when viewed?” preference. To exploit
this vulnerability, an attacker can send a PGP signed email (that is
maliciously crafted) to the Horde user, who then must either view or
preview it.
