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.

	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.

	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.

	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.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

Debian 3.1 (stable)
- -------------------

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

Source archives:

    Size/MD5 checksum:      703 5e723deaccb3db60794e0cb385666992
    Size/MD5 checksum:  2261496 ff19d5500955302455e517cb2942c9d0
    Size/MD5 checksum:    31458 f8fe363e7ccd8fe4072d84cd86a3510e

Architecture independent packages:

    Size/MD5 checksum:  1121200 8fa7064325ded44e7f8dbd226b81d9dd
    Size/MD5 checksum:  1097552 34d96210d581dde8ffea7be82e0897f4

  These files will probably be moved into the stable distribution on
  its next update.
