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.

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.
