Vulnerability Assessment Details
Webmin, Usermin: Format string vulnerability
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200512-02
(Webmin, Usermin: Format string vulnerability)
Jack Louis discovered that the Webmin and Usermin "miniserv.pl"
web server component is vulnerable to a Perl format string
vulnerability. Login with the supplied username is logged via the Perl
"syslog" facility in an unsafe manner.
A remote attacker can trigger this vulnerability via a specially
crafted username containing format string data. This can be exploited
to consume a large amount of CPU and memory resources on a vulnerable
system, and possibly to execute arbitrary code of the attacker's choice
with the permissions of the user running Webmin.
There is no known workaround at this time.
All Webmin users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/webmin-1.250"
All Usermin users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/usermin-1.180"
Network Security Threat Level: High
