Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200502-30
(cmd5checkpw: Local password leak vulnerability)

Florian Westphal discovered that cmd5checkpw is installed setuid
cmd5checkpw but does not drop privileges before calling execvp(), so
the invoked program retains the cmd5checkpw euid.

Impact :

Local users that know at least one valid /etc/poppasswd user/password
combination can read the /etc/poppasswd file.

Workaround :

There is no known workaround at this time.
