GnuPG public keys code execution
|gnupg-public-keys-code-exec (80990)||High Risk|
GnuPG could allow a remote attacker to execute arbitrary code on the system, caused by an access violation error when validating public keys that have been manipulated. By persuading a victim to open a specially-crafted zip file, an attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service.
