Synopsis

The remote FTP server is affected by a local buffer overflow vulnerability.

Description

The remote host is using ProFTPD, a free FTP server for Unix and Linux.

According to its banner, the version of ProFTPD installed on the remote host is earlier than 1.3.1rc1 and is affected by a local, stack-based buffer overflow. The function 'pr_ctrls_recv_request' in the file 'src/ctrls.c' belonging to the 'mod_ctrls' module does not properly handle large values in the 'reqarglen' parameter.

This error can allow a local attacker to execute arbitrary code.

Solution

Upgrade to ProFTPD version 1.3.1rc1 or later.
