Only OpenSSL versions 1.0.1 and 1.0.2-beta releases (including 1.0.1f and 1.0.2-beta1) are affected by the "Heartbleed" bug (CVE-2014-0160). Versions below 1.0.1 (such as 0.9.8) are not affected.
Resolution
Symantec Encryption Desktop, Symantec Drive Encryption, PGP Desktop, and PGP Whole Disk Encryption do not utilize openssl and therefore are not vulnerable to this attack.
