[slackware-security] httpd

New httpd packages are available for Slackware 12.0, 12.1, 12.2, 13.0,
and -current to fix security issues.

mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
by rejecting any client-initiated renegotiations.

mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
when request headers indicate a request body is incoming; not a case of
HTTP_INTERNAL_SERVER_ERROR.

mod_isapi: Do not unload an isapi .dll module until the request processing
is completed, avoiding orphaned callback pointers.
[This is the most serious flaw, but does not affect Linux systems]

Vulnerabilities and Exposures (CVE) database:

Where to find the new packages:

HINT: Getting slow download speeds from ftp.slackware.com?
Give slackware.osuosl.org a try. This is another primary FTP site
for Slackware that can be considerably faster than downloading
directly from ftp.slackware.com.

Thanks to the friendly folks at the OSU Open Source Lab
(http://osuosl.org) for donating additional FTP and rsync hosting
to the Slackware project! :-)

Also see the “Get Slack” section on http://slackware.com for
additional mirror sites near you.

Installation instructions:

Upgrade the package as root:
> upgradepkg httpd-2.2.15-x86_64-1_slack13.0.txz

Then, restart apache httpd:
> sh /etc/rc.d/rc.httpd stop
> sh /etc/rc.d/rc.httpd start

Note that using the “restart” option might not work, as the parent httpd
process continues to run and may be unable to load the new httpd modules.
Therefore, using “stop” and then “start” is recommended.
