The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200603-08
(GnuPG: Incorrect signature verification)
OpenPGP is the standard that defines the format of digital
signatures supported by GnuPG. OpenPGP signatures consist of multiple
sections, in a strictly defined order. Tavis Ormandy of the Gentoo
Linux Security Audit Team discovered that certain illegal signature
formats could allow signed data to be modified without detection. GnuPG
has previously attempted to be lenient when processing malformed or
legacy signature formats, but this has now been found to be insecure.
A remote attacker may be able to construct or modify a
digitally-signed message, potentially allowing them to bypass
authentication systems, or impersonate another user.
There is no known workaround at this time.
