The second component, referred to as CBC/CFB gadget attack, potentially allows an attacker to send malformed data blocks that, when read by the target, would fool the email client into sending to the attacker's server the unencrypted contents of the message.
Security researchers have gone public with vulnerabilities in some secure mail apps that can be exploited by miscreants to decrypt intercepted PGP-encrypted messages.
"Securely encrypted e-mail remains an important and suitable means of increasing information security", it said in a statement, adding that the flaws which have been discovered can be remedied through patches and proper use. Within hours, the researchers published the paper, which is titled Efail: Breaking S/MIME and OpenPGP Email Encryption using Exfiltration Channels.
"In response to that, they said that they did a simple rollback to the non-MDC encryption", he said.
The attacker changes an encrypted email in a particular way and sends this changed encrypted email to the victim. Koch for instance said that OpenPGP's message authentication that thwarts EFAIL (in place since 2001) can't be made mandatory because "some implementations haven't kept up".
Security researchers are warning anyone who uses PGP (Pretty Good Privacy) or S/MIME for email encryption to disable the scheme in their email clients right away, and to uninstall tools that automatically decrypt PGP-encrypted email, due to a security flaw.
Another way would be to use authenticated encryption via tools such as OpenPGP, he argued.
But while that advice might be easier to implement for anyone who uses and configures their own PGP tools, it fails to address how secure webmail providers might address the flaws. And many corporate email services employ S/MIME.
The flaws, some of which have existed for more than a decade, are part of a series of vulnerabilities dubbed "Efail".
