Trustix Secure Linux Security Advisory #2005-0028

Package name: kerberos5, mailman, mod_perl, openssl, php, spamassassin, tcpdump, telnet, wget
Summary: Multiple security updates
Date: 2005-06-13
Affected versions: Trustix Secure Linux 2.1
Trustix Secure Linux 2.2
Trustix Operating System - Enterprise Server 2

- ------------------------------------------------------------------------
--
Package description:
kerberos5:
(MIT) Kerberos is a network authentication protocol. It is designed to
provide strong authentication for client/server applications by using
secret-key cryptography. A free implementation of this protocol is
available from the Massachusetts Institute of Technology. Kerberos is
available in many commercial products as well.

mailman:
Mailman is software to help manage email discussion lists, much like
Majordomo and Smartmail. Unlike most similar products, Mailman gives
each mailing list a webpage, and allows users to subscribe,
unsubscribe, etc. over the Web. Even the list manager can administer
his or her list entirely from the Web. Mailman also integrates most
things people want to do with mailing lists, including archiving, mail
<-> news gateways, and so on.

When the package has finished installing, you sould read README.TRUSTIX for
further instructions.

Users upgrading from previous releases of this package may need to
move their data or adjust the configuration files to point to the
locations where their data is.

mod_perl:
Mod_perl incorporates a Perl interpreter into the Apache web server,
so that the Apache web server can directly execute Perl code.
Mod_perl links the Perl runtime library into the Apache web server and
provides an object-oriented Perl interface for Apache's C language
API. The end result is a quicker CGI script turnaround process, since
no external Perl interpreter has to be started.

Install mod_perl if you're installing the Apache web server and you'd
like for it to directly incorporate a Perl interpreter.

openssl:
A C library that provides various crytographic algorithms and protocols,
including DES, RC4, RSA, and SSL. Includes shared libraries.

php:
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.

spamassassin:
SpamAssassin provides you with a way to reduce, if not completely
eliminate, Unsolicited Bulk Email (or "spam") from your incoming email.
It can be invoked by a MDA such as sendmail or postfix, or can be called
from a procmail script, .forward file, etc. It uses a
genetic-algorithm-evolved scoring system to identify messages which look
spammy, then adds headers to the message so they can be filtered by the
user's mail reading software. This distribution includes the
spamd/spamc components which considerably speeds processing of mail.

tcpdump:
Tcpdump is a command-line tool for monitoring network traffic.
Tcpdump can capture and display the packet headers on a particular
network interface or on all interfaces. Tcpdump can display all of
the packet headers, or just the ones that match particular criteria.

Install tcpdump if you need a program to monitor network traffic.

telnet:
Telnet is a popular protocol for logging into remote systems over the
Internet. The telnet package provides a command line telnet client.

Install the telnet package if you want to telnet to remote machines.

wget:
GNU Wget is a file retrieval utility which can use either the HTTP or
FTP protocols. Wget features include the ability to work in the
background while you're logged out, recursive retrieval of
directories, file name wildcard matching, remote file timestamp
storage and comparison, use of Rest with FTP servers and Range with
HTTP servers to retrieve files over slow or unstable connections,
support for Proxy servers, and configurability.

Install wget if you need to retrieve large numbers of files with HTTP or
FTP, or if you need a utility for mirroring web sites or FTP directories.

Problem description:
kerberos5:
- Security Fix: Buffer overflows in telnet client
- The telnet client program supplied with MIT Kerberos 5 has buffer
overflows in the functions slc_add_reply() and env_opt_add(), which
may lead to remote code execution.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-0469 and CAN-2005-0468 to this issue.

mailman:
- Fixing spool fcron directory for mailman
- Cleanup of byte compiled python modules from spec
- /etc/postfix/aliases should be updated with mailman settings
- Restart only on upgrade situation, otherwise off.

mod_perl:
- Rebuilt on perl for effect changes in CGI.pm

openssl:
- Security Fix: Colin Percival reported a cache timing attack that could
be used to allow a malicious local user to gain portions of
cryptographic keys. The OpenSSL library has been patched to add a new
fixed-window mod_exp implementation as default for RSA, DSA, and DH
private key operations. The patch was designed to mitigate cache
timing and possibly related attacks.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-0109 to this issue.

php:
- Added libxml2-devel, freetype, mhash-devel in buildrequires
Bug #877

spamassassin:
- New upstream

tcpdump:
- Fixed DOS Vulnerability, A vulnerability was identified in tcpdump,
which may be exploited by attackers to cause a denial of service. This
flaw resides in the "bgp_update_print()" function (print-bgp.c) that
does not properly handle a specially crafted value returned by the
"decode_prefix4()" function when processing BGP packets, which may be
exploited by a remote attacker to cause the application to crash.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-1267 to this issue.

telnet:
- Security Fix: Buffer overflows in telnet client
- The telnet client program supplied with MIT Kerberos 5 has buffer
overflows in the functions slc_add_reply() and env_opt_add(), which
may lead to remote code execution.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-0469 and CAN-2005-0468 to these issues.

wget:
- Security Fix: wget allows a remote malicious web server to overwrite
certain files via a redirection URL containing a ".." that resolves to
the IP address of the malicious server, which bypasses wget's filtering
for ".." sequences.
- wget does not filter or quote control characters when displaying HTTP
responses to the terminal, which may allow remote malicious web servers
to inject terminal escape sequences and execute arbitrary code.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-1487 and CAN-2004-1487 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.
