                Mandrake Linux Security Update Advisory

Package name:           mod_ssl
Advisory ID:            MDKSA-2002:072
Date:                   October 24th, 2002
Affected versions:      7.2, 8.0, 8.1, 8.2, 9.0,
                        Single Network Firewall 7.2

Problem Description:

 A cross-site scripting vulnerability was discovered in mod_ssl by Joe
 Orton.  This only affects servers using a combination of wildcard DNS
 and "UseCanonicalName off" (which is not the default in Mandrake
 Linux).  With this setting turned off, Apache will attempt to use the
 hostname:port that the client supplies, which is where the problem
 comes into play.  With this setting turned on (the default), Apache
 constructs a self-referencing URL and will use ServerName and Port to
 form the canonical name.

 It is recommended that all users upgrade, regardless of the setting of
 the "UseCanonicalName" configuration option.
