Trustix Secure Linux Security Advisory #2004-0039
Package name: apache, mod_php4, samba
Summary: Several security vulnerabilities patched
Date: 2004-01-05
Affected versions: Trustix Secure Linux 1.5
Trustix Secure Linux 2.0
Trustix Secure Linux 2.1
Trustix Operating System - Enterprise Server 2
- --------------------------------------------------------------------------
Package description:
apache:
Apache is a full featured web server that is freely available, and also
happens to be the most widely used.
mod_php4:
PHP is an HTML-embedded scripting language. PHP attempts to make it
easy for developers to write dynamically generated web pages. PHP
also offers built-in database integration for several commercial
and non-commercial database management systems, so writing a
database-enabled web page with PHP is fairly simple. The most
common use of PHP coding is probably as a replacement for CGI
scripts. The mod_php module enables the Apache web server to
understand and process the embedded PHP language in web pages.
samba:
Samba provides an SMB server which can be used to provide network
services to SMB (sometimes called "Lan Manager") clients, including
various versions of MS Windows, OS/2, and other Linux machines. Samba
uses NetBIOS over TCP/IP (NetBT) protocols and does NOT need NetBEUI
(Microsoft Raw NetBIOS frame) protocol.
Problem description:
apache:
Recent Apache 2.0 releases place no limit on the amount of folding of
input headers, or in the total length after folding. With an input
stream with infinite headers to be folded, the server will allocate as
much memory as the system will allow leading to a Denial of Service.
This issue was already fixed by a patch in our most recent apache 2.0.49
package. However, we have chosen to upgrade to 2.0.50 to avoid confusion.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-0493 to this issue.
mod_php4:
The php project recomments that older versions of php be updated 4.3.8,
as it fixes several issues. Among these is CAN-2004-0594, also known as
the "memory_limit" bug.
samba:
Two security issues were discovered in samba.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CAN-2004-0600 and CAN-2004-0686 to these issues.
Action:
We recommend that all systems with this package installed be upgraded.
Please note that if you do not need the functionality provided by this
package, you may want to remove it from your system.
