Package : webfs
Vulnerability : buffer overflows, file and directory exposure
Problem-Type : remote
CVE Ids : CAN-2003-0832CAN-2003-0833
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.

in version 1.17.2.
