Subject: [SECURITY] [DSA-087-1] wu-ftpd buffer overflow in glob code
Date:   03 Dec 2001 02:08:41 +0100      


Package        : wu-ftpd
Problem type   : remote root exploit
Debian-specific: no

CORE ST reports that an exploit has been found for a bug in the wu-ftpd
glob code (this is the code that handles filename wildcard expansion).
Any logged in user (including anonymous ftp users) can exploit the bug
to gain root privilege on the server. 

This has been corrected in version 2.6.0-6 of the wu-ftpd package.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.
