Trustix Secure Linux Security Advisory #2005-0059
Package names: apache, lynx, mod_php4, openssl,
php4, php, squid, texinfo, wget
Summary: Multiple vulnerabilities
Date: 2005-10-21
Affected versions: Trustix Secure Linux 2.2
Trustix Secure Linux 3.0
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.
lynx
Lynx is a text-based Web browser. Lynx does not display any images,but
it does support frames, tables and most other HTML tags. Lynx's advantage
over graphical browsers is its speed: Lynx starts and exits quickly and
swiftly when displaying Web pages.
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.
openssl
A C library that provides various crytographic algorithms and protocols,
including DES, RC4, RSA, and SSL. Includes shared libraries.
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.

server to understand and process the embedded PHP language in web pages.
squid
Squid is a high-performance proxy caching server for Web clients,
supporting FTP, gopher, and HTTP data objects. Unlike traditional
caching software, Squid handles all requests in a single, non-blocking,
I/O-driven process. Squid keeps meta data and especially hot objects
cached in RAM, caches DNS lookups, supports non-blocking DNS lookups,
and implements negative caching of failed requests.
texinfo
Texinfo is a documentation system that can produce both online
information and printed output from a single source file. Normally,
you'd have to write two separate documents: one for online help or
other online information and the other for a typeset manual or other
printed work. Using Texinfo, you only need to write one source
document. Then when the work needs revision, you only have to revise
one source document. The GNU Project uses the Texinfo file format for
most of its documentation.
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.
Problem description:
apache < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- New Upstream and Multiple Vendor Security Fixes
- SECURITY Fix: CVE-2005-2700, CVE-2005-2491, CVE-2005-2088, CVE-2005-2728,
CVE-2005-2088, CVE-2005-1268 .
- Fix core dump if mod_auth_ldap's mod_auth_ldap_auth_checker() was called
even if mod_auth_ldap_check_user_id() was not (or if it didn't succeed)
for non-authoritative cases.
- mod_proxy: Fix over-eager handling of '%' for reverse proxies.
- mod_ldap: Fix various shared memory cache handling bugs.
lynx < TSL 2.2 > < TSEL 2 >
- SECURITY Fix: Fix Stack-based buffer overflow in the HTrjis function in
Lynx 2.8.6 and earlier allows remote NNTP servers to execute arbitrary
code via certain article headers that cause Lynx to add extra escape
(ESC) characters.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2005-3120
mod_php4 < TSEL 2 >
- SECURITY Fix: A vulnerability has been identified in PHP, which could be
exploited by malicious users to bypass security policies. This flaw is
due to an error in "fopen_wrappers.c" that does not properly restrict access
to other directories when the "open_basedir" directive includes a trailing
slash, which could allow certain scripts in a directory (e.g."/user/test2/)
to access files in other directories whose names are substrings of the
original directory (e.g. "/user/test22/).
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2005-3054
openssl < TSL 3.0 >
- New Upstream
- SECURITY Fix: Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
(part of SSL_OP_ALL). This option used to disable the countermeasure
against man-in-the-middle protocol-version rollback in the SSL 2.0 server
implementation, which is a bad idea.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2005-2969
php4 < TSL 2.2 >
- SECURITY Fix: A vulnerability has been identified in PHP, which could be
exploited by malicious users to bypass security policies. This flaw is
due to an error in "fopen_wrappers.c" that does not properly restrict access
to other directories when the "open_basedir" directive includes a trailing
slash, which could allow certain scripts in a directory (e.g."/user/test2/)
to access files in other directories whose names are substrings of the
original directory (e.g. "/user/test22/).

squid < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- New Upstream and Multiple Vendor Security Fixes
texinfo < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- SECURITY Fix: Frank Lichtenheld discovered that the "texindex" program
created temporary files in an insecure manner. This could allow a symlink
attack to create or overwrite arbitrary files with the privileges of
the user running texindex.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-3011
wget < TSL 3.0 > < TSL 2.2 > < TSEL 2 >
- New upstream.
- SECURITY Fix: Stack-based buffer overflow in the ntlm_output function in
http-ntlm.c. when NTLM authentication is enabled, allows remote servers to
execute arbitrary code via a long NTLM username.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-3185
