Ubuntu 4.10 / 5.04 / 5.10 : gnupg vulnerability (USN-264-1)

Medium Nessus Plugin ID 21182


The remote Ubuntu host is missing a security-related patch.


Tavis Ormandy discovered a flaw in gnupg's signature verification. In some cases, certain invalid signature formats could cause gpg to report a 'good signature' result for auxiliary unsigned data which was prepended or appended to the checked message part.

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.


Update the affected gnupg package.
