ASCII Armor is a text based encoding format used by PGP (Pretty Good Privacy). While it is possible to encode any file using ASCII Armor, it is used by PGP to encode signature files and public keys to facilitate transmission in e-mail messages.

When a user opens a document for verification in PGP, its corresponding .sig file must be decoded from ASCII Armor.

Due to a flaw in the implementation of the decoder, an arbitrary file can be created on a users system. The file created would be of the attackers choice.

- 漏洞描述

PGP contains a flaw that allows a remote attacker to potentially execute arbitrary code. The issue is due to the ASCII armor parser exctracting binary files which may contain .DLL files, which Windows operating systems can be tricked into executing. If an attacker sends a specially crafted armored attachment, this would allow them to execute arbitrary code or commands via the malicious DLL.
