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:
- ------------------------
