_____________________________________________________________________________________________ TurboLinux Security Announcement Package: analog Vulnerable Packages: All Turbolinux versions previous to 4.16-2 Date: 05/03/2001 5:00 PDT Affected TurboLinux platforms: Turbolinux versions 6.0.5 and earlier TurboLinux Advisory ID#: TLSA2001007 Credits: Vulnerability discovered by Stephen Turner References: http://www.securityfocus.com/vdb/bottom.html?section=discussion&vid=2377 _____________________________________________________________________________________________ A security hole was discovered in the package mentioned above. Please update the package in your installation as soon as possible. _____________________________________________________________________________________________ 1. Problem Summary(From the BugTraq database of securityfocus.com, id#2377) As designed, the software makes it possible for a user to remotely access network statistics using cgi scripts and HTTP FORM methods. When queried, the cgi accesses analog, and outputs statistics to a web page. Due to a buffer overflow in analog, and improper checking of input by the cgi program, it is possible for a user to supply a long ALIAS field to the analog program, which will result in a buffer overflow. 2. Impact(Also from the BugTraq database, id#2377) A user can remotely execute code and execute commands with privileges equal to the httpd process. 3. Solution First, uninstall the package analog-form using the command: rpm -e analog-form-3.0-1.i386.rpm, or whatever version of analog-form you are currently running Then, update the analog package from our ftp server by running the following command: rpm -Uvh ftp_path_to_filename Where ftp_path_to_filename is the following: ftp://ftp.turbolinux.com/pub/updates/6.0/security/analog-4.16-2.i386.rpm The source RPM can be downloaded here: ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/analog-4.16-2.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.
