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

_____________________________________________________________________________________________
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.
Please verify the MD5 checksums of the updates before you install:
MD5 sum Package Name

TurboLinux Security Announcement
Package: ncurses
Vulnerable Packages: All versions previous to 5.2
Date: 05/04/2001 5:00 PDT
Affected TurboLinux versions: TL 6.1 WorkStation,
All TurboLinux versions
6.0.5 and earlier

___________________________________________________________________________
A security hole has been discovered in this package. Please update
the packages in your installation as soon as possible.
___________________________________________________________________________
1. Problem Summary
Ncurses contains buffer overflow vulnerabilities. It searches for
term- cap entries in a file called .terminfo in the home
directory. If it exists, it makes string copies of data in the
file to local buffers in the process' stack. The copy process is
insecure because it does not check to ensure that the amount of
bytes copied does not exceed the pre- determined buffer size.
Therefore, an attacker can easily create a .terminfo file with
excessive data. The excess data would overwrite bytes on the
stack beyond the defined boundary of the buffer when copied.
2. Impact
Attackers may be able to exploit setuid or setgid programs linked
to ncurses and elevate their privileges.
A program linked to ncurses isn't immediately vulnerable. It must
use certain functions within ncurses in some way in order for the
vulnera- bility to be exploitable.
3. Solution
Update each 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/ncurses-5.2-2.i386.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/security/ncurses-devel-5.2-2.i386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/ncurses-5.2-2.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.
