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.


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.
