                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           mod_ssl
Advisory ID:            MDKSA-2002:048
Date:                   August 8th, 2002
Affected versions:      7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1,
                        Single Network Firewall 7.2
________________________________________________________________________

Problem Description:

 Frank Denis discovered an off-by-one error in mod_ssl dealing with the
 handling of older configuration directorives (the rewrite_command
 hook).  A malicious user could use a specially-crafted .htaccess file
 to execute arbitrary commands as the apache user or execute a DoS
 against the apache child processes.

 This vulnerability is fixed in mod_ssl 2.8.10; patches have been
 applied to correct this problem in these packages.
