Ubuntu 6.06 LTS / 6.10 : gnupg2, gpgme1.0 vulnerability (USN-432-2)
Medium Nessus Plugin ID 28027
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-432-1 fixed a vulnerability in GnuPG. This update provides the corresponding updates for GnuPG2 and the GPGME library.
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.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected packages.
