Netwosix Linux Security Advisory #2004-0006 <http://www.netwosix.org>
Package name: apache
Summary: Multiple security vulnerabilities in Apache 2.x
Date: 2004-03-25
Affected versions: Netwosix 1.0 Netwosix 1.1
-> Package description:
The Apache HTTP Server Project is an effort to develop and maintain
an open-source HTTP server for modern operating systems including
UNIX and Windows NT. The goal of this project is to provide a
secure, efficient and extensible server that provides HTTP services
in sync with the current HTTP standards.
-> Problem description:
Apache before 2.0.49, when using multiple listening sockets on
certain platforms, allows remote attackers to cause a denial of
service (blocked new connections) via a “short-lived connection on
a rarely-accessed listening socket.”
Apache does not filter terminal escape sequences from its error
logs, which could make it easier for attackers to insert those
sequences into terminal emulators containing vulnerabilities
related to escape sequences.
Memory leak in ssl_engine_io.c for mod_ssl in Apache 2 before
2.0.49 allows remote attackers to cause a denial of service (memory
consumption) via plain HTTP requests to the SSL port of an
SSL-enabled server.
-> Action:

-> About Linux Netwosix:
Linux Netwosix is a powerful and optimized Linux distribution for
servers and Network Security related jobs. It can also be used for
special operations such as penetration testing with its big
collection of security oriented software and sources. It’s a light
distribution created for the requirements of every SysAdmin and
it’s very portable and highly configurable. Our philosophy is to
give greater liberty for configuration to the SysAdmin. Only in
this way can he/she configure a powerful and stable server machine.
Linux Netwosix also has a powerful ports system (Nepote) similar to
the xBSD systems but more flexible and usable.
