The CERT Coordination Center (CERT/CC) has released information on email client vulnerabilities that can reveal 
plaintext versions of OpenPGP- and S/MIME-encrypted emails. A remote attacker could exploit these vulnerabilities to 
obtain sensitive information.

NCCIC encourages users and administrators to review CERT/CCs Vulnerability Note VU #122919 [ 
https://www.kb.cert.org/vuls/id/122919 ], apply the necessary mitigations, and refer to software vendors for 
appropriate patches, when available.
