Severity: Normal
Title: glFTPd: Local buffer overflow vulnerability
Date: September 21, 2004
Bugs: #64809
ID: 200409-27
Synopsis
=======
glFTPd is vulnerable to a local buffer overflow which may allow
arbitrary code execution.
Background
=========
glFTPd is a highly configurable FTP server with many features.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-ftp/glftpd < 1.32-r1 >= 1.32-r1
==========
The glFTPd server is vulnerable to a buffer overflow in the 'dupescan'
program. This vulnerability is due to an unsafe strcpy() call which can
cause the program to crash when a large argument is passed.
Impact
=====
A local user with malicious intent can pass a parameter to the dupescan
program that exceeds the size of the buffer, causing it to overflow.
This can lead the program to crash, and potentially allow arbitrary
code execution with the permissions of the user running glFTPd, which
could be the root user.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All glFTPd users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=net-ftp/glftpd-1.32-r1"
# emerge ">=net-ftp/glftpd-1.32-r1"
