Of Efail, the maintainers said that users "might be vulnerable if you're running an ancient version of GnuPG (the 1.0 series; the current is 2.2), or if your email plugin doesn't handle GnuPG's warning correctly".
"They might reveal the plaintext of encrypted emails, including encrypted emails sent in the past", researchers said. In a post on Monday, he said his team was not contacted about the flaw and the attack could be mitigated by avoiding HTML emails or using authenticated encryption, which adds a layer of protection to confirm the message has not been changed.
German and Belgian researchers have warned of potential attacks that break email encryption using Pretty Good Privacy (PGP) and secure multi-purpose internet mail extensions (S/MIME) by coercing clients into sending the full plaintext of the emails to the attacker. "You are thus only affected if an attacker already has access to your emails". Then the emails are changed in a particular way and sent to a victim. This is then encrypted with the sender's private "key" and decrypted by the receiver using a separate public key. So, users guides for email clients Thunderbird, Apple Mail and Outlook.
"It's a lot of steps for sure, and one that honestly is more hypothetical than is it is unsafe", Dave Kennedy, the chief executive at security company TrustedSec, said.
The researchers have published a paper on how encrypted emails can be turned into plaintext.
"Our advice, which mirrors that of the researchers, is to immediately disable and/or uninstall tools that automatically decrypt PGP-encrypted email". The Electronic Frontier Foundation (EFF) recently claimed that the encryption bug posed "an immediate risk" to PGP and S/Mime users, and that even ancient messages buried deep inside elaborately named folders are in danger.
Users should for now switch to non-e-mail-based secure messaging apps for sensitive communications.
"This is bad because the people who use PGP use it for a reason", he told the BBC.
In the future, patches should prevent this PGP flaw from being exploited. The PGP CFB gadget attack was assigned CVE-2017-17688, while the S/MIME CBC vulnerability was given CVE-2017-17689. Because the HTML rendering engine is enabled, this prompts the mail client to treat the message body as a URL, which it encodes and queries the malicious actor's server, thereby leaking the message.
