RHSA-2008:0005 - Security Advisory

Topic

Updated Apache httpd packages that fix several security issues are now
available for Red Hat Enterprise Linux 3.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

The Apache HTTP Server is a popular Web server.

A flaw was found in the mod_imap module. On sites where mod_imap was
enabled and an imagemap file was publicly available, a cross-site scripting
attack was possible. (CVE-2007-5000)

A flaw was found in the mod_autoindex module. On sites where directory
listings are used, and the "AddDefaultCharset" directive has been removed
from the configuration, a cross-site scripting attack was possible against
Web browsers which did not correctly derive the response character set
following the rules in RFC 2616. (CVE-2007-4465)

A flaw was found in the mod_proxy module. On sites where a reverse proxy is
configured, a remote attacker could send a carefully crafted request that
would cause the Apache child process handling that request to crash. On
sites where a forward proxy is configured, an attacker could cause a
similar crash if a user could be persuaded to visit a malicious site using
the proxy. This could lead to a denial of service if using a threaded
Multi-Processing Module. (CVE-2007-3847)

A flaw was found in the mod_status module. On sites where mod_status was
enabled and the status pages were publicly available, a cross-site
scripting attack was possible. (CVE-2007-6388)

A flaw was found in the mod_proxy_ftp module. On sites where mod_proxy_ftp
was enabled and a forward proxy was configured, a cross-site scripting
attack was possible against Web browsers which did not correctly derive the
response character set following the rules in RFC 2616. (CVE-2008-0005)

Users of Apache httpd should upgrade to these updated packages, which
contain backported patches to resolve these issues. Users should restart
httpd after installing this update.
