Vulnerabilities could reveal plaintext of encrypted emails, European security researchers say. PGP/GPG and S/MIME encryption techniques used to encrypt emails and data are vulnerable to the flaws.

The flaws could allow attackers to exfiltrate data “for 23 of the 35 tested S/.MIME email clients and 10 of the 28 tested OpenPGP email clients””]
