Originalnachricht

New Apache packages for Slackware are available to fix a security issue.

>From the Apache site:

"While testing for Oracle vulnerabilities, Mark Litchfield discovered a
denial of service attack for Apache on Windows. Investigation by the
Apache Software Foundation showed that this issue has a wider scope, which
on some platforms results in a denial of service vulnerability, while on
some other platforms presents a potential a remote exploit vulnerability."

The complete text of the Apache announcement may be found here:
http://httpd.apache.org/info/security_bulletin_20020617.txt

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0392 to this issue:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0392


SOLUTION
--------

We recommend that sites providing external Apache access upgrade to the fixed
Apache package as soon as possible. If you are using mod_ssl, you will also
require an updated mod_ssl package. Updated packages have been prepared for
Slackware 8.0 and 8.1.
