Package        : webmin
Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2004-0582 CAN-2004-0583

Two vulnerabilities were discovered in webmin:

CAN-2004-0582: Unknown vulnerability in Webmin 1.140 allows remote
 attackers to bypass access control rules and gain read access to
 configuration information for a module.

CAN-2004-0583: The account lockout functionality in (1) Webmin 1.140
 and (2) Usermin 1.070 does not parse certain character strings, which
 allows remote attackers to conduct a brute force attack to guess user
 IDs and passwords.

For the current stable distribution (woody), these problems have been
fixed in version 0.94-7woody2.

For the unstable distribution (sid), these problems have been fixed in
version 1.150-1.

We recommend that you update your webmin package.
