Vulnerability Scan Summary
cmd5checkpw: Local password leak vulnerability
Detailed Explanation for this Vulnerability Test
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
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.
Solution:
All cmd5checkpw users should upgrade to the latest available
version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-mail/cmd5checkpw-0.22-r2"
Threat Level: Low
