Network Associates PGP Keyserver 7.0 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via exceptional BER encodings (possibly buffer overflows), as demonstrated by the PROTOS LDAPv3 test suite.

The split key mechanism used by PGP 7.0 allows a key share holder to obtain access to the entire key by setting the "Cache passphrase while logged on" option and capturing the passphrases of other share holders as they authenticate.

The OpenPGP PGP standard allows an attacker to determine the private signature key via a cryptanalytic attack in which the attacker alters the encrypted private key file and captures a single message signed with the signature key.

ASCII Armor parser in Windows PGP 7.0.3 and earlier allows attackers to create files in arbitrary locations via a malformed ASCII armored file.

PGP 5.5.x through 6.5.3 does not properly check if an Additional Decryption Key (ADK) is stored in the signed portion of a public certificate, which allows an attacker who can modify a victim's public certificate to decrypt any data that has been encrypted with the modified certificate.

The BAIR program does not properly restrict access to the Internet Explorer Internet options menu, which allows local users to obtain access to the menu by modifying the registry key that starts BAIR.

The command port for PGP Certificate Server 2.5.0 and 2.5.1 allows remote attackers to cause a denial of service if their hostname does not have a reverse DNS entry and they connect to port 4000.

The pgpk command in PGP 5.x on Unix systems uses an insufficiently random data source for non-interactive key pair generation, which may produce predictable keys.
