CONECTIVA LINUX SECURITY ANNOUNCEMENT
-----------------------------------------------------------------------
PACKAGE : apache
SUMMARY : mod_rewrite and Host header vulnerability
DATE : 2000-10-11 16:19:00
RELEVANT
RELEASES : 4.0, 4.0es, 4.1, 4.2, 5.0, prg gráficos, ecommerce, 5.1

DESCRIPTION
There are two vulnerabilities in the Apache web server as shipped
with Conectiva Linux.
1) Under certain configurations, the mod_rewrite module could be used
to access any file on the server, provided that filesystem access
rights permitted that. Now the mod_rewrite module makes a one-pass
expansion and is no longer vulnerable to this.
2) The other vulnerability is regarding the handling of Host: headers
in mass virtual hosting configurations. The check for dot (".")
charactes in that header was not complete and could permit access to
a parent directory.
SOLUTION
It is recommended that users using mod_rewrite or with virtual
hosting update their servers.
Users of Conectiva Linux 4.1 and 4.2 will also find apache-1.3.12 on
the FTP site. That package should be used for those who upgraded to
1.3.12 because of the IMP/HORDE advisory a while ago.
