GnuPG Private Key Silent Import
Local Access Required Cryptographic
Loss of Integrity
Exploit Public

- 漏洞描述

GnuPG contains a flaw that may allow a malicious user to compromise the web of trust. The issue is triggered when the user retrieves keys from a public keyserver. GnuPG will import private keys as well as public ones, and will not warn the user about the import of private keys. An attacker can upload a private key to the keyserver as well as a public one, with malicious intent. Since private keys are implicitly trusted, it is possible that the flaw may allow a change in the trust relationships of the web of trust, resulting in a loss of integrity.
