gprostats, distributed with GProFTPD, is vulnerable to a format string vulnerability, potentially leading to the execution of arbitrary code.

2.  Impact Information


GProFTPD is a GTK+ administration tool for the ProFTPD server. GProFTPD is distributed with gprostats, a utility to parse ProFTPD transfer logs.


Tavis Ormandy of the Gentoo Linux Security Audit Team has identified a format string vulnerability in the gprostats utility.


An attacker could exploit the vulnerability by performing a specially crafted FTP transfer, the resulting ProFTPD transfer log could potentially trigger the execution of arbitrary code when parsed by GProFTPD.

3.  Resolution Information


There is no known workaround at this time.


All GProFTPD users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
