cmd5checkpw: Local password leak vulnerability

Detailed Explanation for this Vulnerability Assessment
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 rights before calling execvp(), so

user/password combination can read the /etc/poppasswd file.

Workaround

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-mail/cmd5checkpw-0.22-r2"
