GnuPG duplicate keys code execution
| gnupg-keys-code-execution (41547) |  High Risk |
Description:
GnuPG could allow a remote attacker to execute arbitrary code on the system, caused by a memory corruption error while duplicating user IDs. By importing OpenPGP keys from key servers using specially-crafted duplicate keys, a remote attacker could exploit this vulnerability to corrupt memory and execute arbitrary code or cause a denial of service.
