Ubuntu: GnuPG2, GPGME vulnerability Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Ubuntu USN-432-1 fixed a vulnerability in GnuPG. This update provides the corresponding updates for GnuPG2 and the GPGME library. Original advisory details: Gerardo Richarte from Core Security Technologies discovered that when gnupg is used without --status-fd, there is no way to distinguish initial unsigned messages from a following signed message. An attacker could inject an unsigned message, which could fool the user into thinking the message was entirely signed by the original sender.
