In the Bugtraq database (at SecurityFocus): BugTraq ID 15629, BugTraq ID 18744, BugTraq ID 19820. In Mitre's CVE dictionary: CVE-2005-3912, CVE-2006-3392, CVE-2006-4542. 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) Source: http://security.debian.org/pool/updates/main/w/webmin/webmin_1.180-3sarge1.dsc http://security.debian.org/pool/updates/main/w/webmin/webmin_1.180.orig.tar.gz http://security.debian.org/pool/updates/main/w/webmin/webmin_1.180-3sarge1.diff.gz Architecture-independent component: http://security.debian.org/pool/updates/main/w/webmin/webmin-core_1.180-3sarge1_all.deb http://security.debian.org/pool/updates/main/w/webmin/webmin_1.180-3sarge1_all.deb MD5 checksums of the listed files are available in the original advisory.
