Details

Evgeny Legerov discovered that gnupg did not sufficiently check the
validity of the comment and a control field. Specially crafted GPG
data could cause a buffer overflow. This could be exploited to execute
arbitrary code with the user's privileges if an attacker can trick an
user into processing a malicious encrypted/signed document with gnupg.
