Apple Mail any version

Unspecified vulnerability in Mail in Apple Mac OS X 10.4.11 allows remote attackers to execute arbitrary commands via a crafted file:// URL.

The OpenPGP specification allows a Cipher Feedback Mode (CFB) malleability-gadget attack that can indirectly lead to plaintext exfiltration, aka EFAIL. NOTE: third parties report that this is a problem in applications that mishandle the Modification Detection Code (MDC) feature or accept an obsolete packet type, not a problem in the OpenPGP specification

The S/MIME specification allows a Cipher Block Chaining (CBC) malleability-gadget attack that can indirectly lead to plaintext exfiltration, aka EFAIL.

The Limit Mail feature in the Parental Controls functionality in Mail on Apple Mac OS X does not properly enforce the correspondence whitelist, which allows remote attackers to bypass intended access restrictions and conduct e-mail communication by leveraging knowledge of a child's e-mail address and a parent's e-mail address, related to parental notification of unapproved e-mail addresses.

Mail.app in Mac OS 10.4.2 and earlier, when printing or forwarding an HTML message, loads remote images even when the user's preferences state otherwise, which could result in a privacy leak.
