GnuPG Multiply Signed Message Document Modification
Local Access Required, Remote / Network Access Cryptographic
Loss of Integrity
Exploit Public

- 漏洞描述

GnuPG contains a flaw that may allow a malicious attacker to modify documents in a signed message without changing the apparent signatures. The issue is triggered when a message with multiple cleartext signatures and multiple attached documents is created. GnuPG does not compare each signature for each document in the message, but instead flags each document as good or bad depending on the first document in the file. It is possible that this flaw may allow an attacker to surreptitiously modify any document but the first, resulting in a loss of integrity.
