Description Martin Prpič 2015-06-02 05:07:18 EDT 
It was reported that the hp-plugin utility, included in the hplip package, downloads a binary driver and verifies it via a key specified by the key's short ID:

Downloading plug-in: [\                                   ] 0% Receiving digital keys: /bin/gpg --homedir /home/test/.hplip/.gnupg --no-permission-warning --keyserver pgp.mit.edu --recv-keys 0xA59047B9

A man-in-the-middle attacker could use this flaw to generate a key with the expected short ID and trick a user into downloading a malicious binary.
