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.
