Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           apache2
Advisory ID:            MDKSA-2003:050
Date:                   April 22nd, 2003

Affected versions: 9.1
________________________________________________________________________

Problem Description:

A memory leak was discovered in Apache 2.0 through 2.0.44 that can
allow a remote attacker to cause a significant denial of service
(DoS) by sending requests containing a lot of linefeed characters to
the server.


As well, Apache does not filter terminal escape sequences from its
log files, which could make it easy for an attacker to insert those
sequences into the error and access logs, which could possibly be
viewed by certain terminal emulators with vulnerabilities related to
escape sequences.


After upgrading these packages, be sure to restart the httpd server
by executing:


service httpd restart
