Vulnerability from variot
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. In multiple mail clients OpenPGP and S/MIME A plaintext message may be leaked when decrypting the message. OpenPGP and S/MIME For e-mail clients that support, it is possible to establish a channel for sending plaintext by decrypting encrypted e-mail inserted with content crafted by an attacker with the user's e-mail client. The discoverer can attack with this vulnerability "CBC/CFB gadget attack" I call it. For example HTML image By inserting a tag, the decrypted message is HTTP It may be sent as part of the request. * CVE-2017-17688: OpenPGP CFB Attacks * CVE-2017-17689: S/MIME CBC Attacks Some email clients also use multipart MIME Because the message is not properly separated and processed, attackers can process encrypted mail in plain text. MIME It can be included in the part. in this case, CBC/CFB gadget attack The plaintext message may be sent without executing. Detail is, Articles provided by the discoverer Please refer to.A remote attacker may obtain plaintext from encrypted mail without the key information required for decryption. OpenPGP is prone to an information disclosure vulnerability. An attacker can exploit this issue to perform man-in-the-middle attacks and obtain sensitive information. Successful exploits will lead to other attacks. OpenPGP is a set of email encryption standards that supports multiple platforms
