Package : webmin
Vulnerability : multiple
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2005-3912 CVE-2006-3392 CVE-2006-4542
BugTraq ID : 15629 18744 19820
Debian Bug : 341394 381537 391284

Several vulnerabilities have been identified in webmin, a web-based
administration toolkit.

CVE-2005-3912
A format string vulnerability in miniserv.pl could allow an
attacker to cause a denial of service by crashing the
application or exhausting system resources, and could
potentially allow arbitrary code execution.

CVE-2006-3392
Improper input sanitization in miniserv.pl could allow an
attacker to read arbitrary files on the webmin host by providing
a specially crafted URL path to the miniserv http server.

CVE-2006-4542
Improper handling of null characters in URLs in miniserv.pl
could allow an attacker to conduct cross-site scripting attacks,
read CGI program source code, list local directories, and
potentially execute arbirary code.

For the stable distribution (sarge), these problems have been fixed in
version 1.180-3sarge1

Webmin is not included in unstable (sid) or testing (etch), so these
problems are not present.

We recommend that you upgrade your webmin (1.180-3sarge1) package.
