Package        : moxftp
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no
CVE Id         : CAN-2003-0203

Knud Erik Højgaard discovered a vulnerability in moxftp (and xftp
respectively), an Athena X interface to FTP.  Insufficient bounds
checking could lead to execution of arbitrary code, provided by a
malicious FTP server.   Erik Tews fixed this.

For the stable distribution (woody) this problem has been fixed in
version 2.2-18.1.

For the old stable distribution (potato) this problem has been fixed
in version 2.2-13.1.

For the unstable distribution (sid) this problem has been fixed
in version 2.2-18.20.

We recommend that you upgrade your xftp package.
