Turbolinux Security Announcement
Package : wu-ftpd Vulnerable Packages: Versions previous to wu-ftpd-2.6.1-10 Date: Wed Jan 23 12:26:21 PST 2002
Affected Turbolinux versions: previous to wu-ftpd-2.6.1-10
Turbolinux Advisory ID#: TLSA2002002
Credits: http://www.debian.org/security/2001/dsa-087 ___________________________________________________________________________
A security hole was discovered in the package mentioned above. Please update the package in your installation as soon as possible. ___________________________________________________________________________
1. Problem Summary
CORE ST reports that an exploit has been found for a bug in the wu-ftpd glob code. This is the code that handles filename wild card expansion.
2. Impact
Any logged in user (including anonymous FTP users) can exploit the bug to gain root privileges on the server.
3. Solution
This has been corrected in version wu-ftpd-2.6.1-10
Update the package from our ftp server by running the following command:
rpm -Uvh ftp://ftp.turbolinux.com/pub/updates/6.0/security/<rpm>
Where <rpm> are the following:
wu-ftpd-2.6.1-10.i386.rpm
The source RPM can be downloaded from:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/wu-ftpd-2.6.1-10.src.rpm
**Note: You must rebuild and install the RPM if you choose to download and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE THE SECURITY HOLE.
Please verify the MD5 checksums of the updates before you install:
MD5 sum Package Name --------------------------------------------------------------------------- 370d61d7c3a74180a1532bf462a460de wu-ftpd-2.6.1-10.i386.rpm 1d259c40e1c744d72d8bb8724f9ebe47 wu-ftpd-2.6.1-10.src.rpm ___________________________________________________________________________
These packages are GPG signed by Turbolinux for security. Our key is available here:
http://www.turbolinux.com/security/tlgpgkey2002-01-09.asc
To verify a package, use the following command:
rpm --checksig name_of_rpm
To examine only the md5sum, use the following command:
rpm --checksig --nogpg name_of_rpm
**Note: Checking GPG keys requires RPM 3.0 or higher.
