Vulnerability CVE-2011-0418


Published: 2011-05-24   Modified: 2011-09-21

Description:
The glob implementation in Pure-FTPd before 1.0.32, and in libc in NetBSD 5.1, does not properly expand expressions containing curly brackets, which allows remote authenticated users to cause a denial of service (memory consumption) via a crafted FTP STAT command.
