Code injection

mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the "--status-fd 2" option. For example, the OpenPGP data might represen...

E-Mail Vulnerabilities and Disclosure

Last week, researchers disclosed vulnerabilities in a large number of encrypted e-mail clients: specifically, those that use OpenPGP and S/MIME, including Thunderbird and AppleMail. These are serious vulnerabilities: An attacker who can alter mail sent to a vulnerable client can trick that client...
