Description:
A buffer overflow vulnerability was reported in the ProFTPD FTP server. A remote user with upload privileges may be able to obtain root access on the target system.
Internet Security Systems reported that there is a flaw in the processing of inbound ASCII file transfers. A remote user with upload privileges can upload a specially crafted file in ASCII mode and then attempt to download the file to trigger the buffer overflow and execute arbitrary code. The remote user can bypass ProFTPD security checks to cause the code to execute with root level privileges, the report said.
According to the report, the flaw resides in the translation of newline characters.
The CVE number CAN-2003-0831 has been assigned to this issue.

Impact:
A remote user with file upload privileges can execute arbitrary code on the target system with root privileges.

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.
