Mandrake Linux Security Update Advisory
_______________________________________________________________________

Package name: proftpd
Advisory ID: MDKSA-2003:095-1
Date: December 31st, 2003
Original Advisory Date: September 26th, 2003
Affected versions: 9.1, 9.2
______________________________________________________________________

Problem Description:

A vulnerability was discovered by X-Force Research at ISS in ProFTPD's
handling of ASCII translation. An attacker, by downloading a carefully
crafted file, can remotely exploit this bug to create a root shell.

The ProFTPD team encourages all users to upgrade to version 1.2.7 or
higher. The problematic code first appeared in ProFTPD 1.2.7rc1, and
the provided packages are all patched by the ProFTPD team to protect
against this vulnerability.

Update:

The previous update had a bug where the new packages would terminate
with a SIGNAL 11 when the command "NLST -alL" was performed in
certain cases, such as if the size of the output of the command was
greater than 1024 bytes.

These updated packages have a fix applied to prevent this crash.
