The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200602-10
(GnuPG: Incorrect signature verification)
Tavis Ormandy of the Gentoo Linux Security Auditing Team
discovered that automated systems relying on the return code of GnuPG
or gpgv to authenticate digital signatures may be misled by malformed
signatures. GnuPG documentation states that a return code of zero (0)
indicates success, however gpg and gpgv may also return zero if no
signature data was found in a detached signature file.
An attacker may be able to bypass authentication in automated
systems relying on the return code of gpg or gpgv to authenticate
There is no known workaround at this time.
