[原文]Format string vulnerability in Gnu Privacy Guard (aka GnuPG or gpg) 1.05 and earlier can allow an attacker to gain privileges via format strings in the original filename that is stored in an encrypted file.
GnuPG is a popular open source public/private key encryption system.
It is possible for attackers to create an encrypted document that will exploit a format string vulnerability in the GnuPG client when the document is decrypted.
This vulnerability may lead to remote attackers gaining access to client hosts.

Loss of Integrity
GnuPG contains a flaw that may allow a malicious user to execute arbitrary code in the context of a user decrypting a given file. The issue is triggered when the attacker sends the victim a GPG message with a crafted filename, exploiting a format string vulnerability in the tty_printf() function. It is possible that the flaw may allow execution of code in the context of the target user, resulting in a loss of integrity.
Upgrade to version 1.0.6 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
