Debian DSA-392-1 : webfs - buffer overflows, file and directory exposure
high Nessus Plugin ID 15229
Synopsis
The remote Debian host is missing a security-related update.Description
Jens Steube reported two vulnerabilities in webfs, a lightweight HTTP server for static content.CAN-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.
CAN-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 CAN-2003-0832, this could be a world-writable directory such as /var/tmp.
Solution
For the current stable distribution (woody) these problems have been fixed in version 1.17.2.We recommend that you update your webfs package.
