cmd5checkpw is a checkpassword compatible authentication program that
uses CRAM-MD5 authentication mode.
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 type="low">
Local users that know at least one valid /etc/poppasswd user/password
combination can read the /etc/poppasswd file.
There is no known workaround at this time.
All cmd5checkpw users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-mail/cmd5checkpw-0.22-r2&quot;</code>
