EFAIL: OpenPGP Cipher Feedback Mode (CFB) Vulnerability

CVE-2017-17688 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:N/A:N

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
