Summary

The remote host is missing an update to webfs announced via advisory DSA 392-1.

Insight

Insight

Jens Steube reported two vulnerabilities in webfs, a lightweight HTTP server for static content. CVE-2003-0832 - When virtual hosting is enabled, a remote client could specify '..' as the hostname in a request, allowing retrieval of directory listings or files above the document root. CVE-2003-0833 - A long pathname could overflow a buffer allocated on the stack, allowing execution of arbitrary code. In order to exploit this vulnerability, it would be necessary to be able to create directories on the server in a location which could be accessed by the web server. In conjunction with CVE-2003-0832, this could be a world-writable directory such as /var/tmp. For the current stable distribution (woody) these problems have been fixed in version 1.17.2. For the unstable distribution (sid) these problems have been fixed in version 1.20. We recommend that you update your webfs package.
