Package : webfs
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE Id : CAN-2003-0445
webfs, a lightweight HTTP server for static content, contains a buffer
overflow whereby a long Request-URI in an HTTP request could cause
arbitrary code to be executed.
For the stable distribution (woody) this problem has been fixed in
version 1.17.1.
The old stable distribution (potato) does not contain a webfs package.
For the unstable distribution (sid) this problem will be fixed soon.
We recommend that you update your webfs package.
