Debian Security Advisory

DSA-1199-1 webmin -- multiple vulnerabilities

Date Reported:

Security database references:

In the Debian bugtracking system: Bug 341394, Bug 381537, Bug 391284.

More information:

Several vulnerabilities have been identified in webmin, a web-based administration toolkit. The Common Vulnerabilities and Exposures project identifies the following vulnerabilities:

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 arbitrary code.

Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, m68k, mips, mipsel, powerpc, s390 and sparc.

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.

Fixed in:

Debian GNU/Linux 3.1 (stable)
