#178221 — apache2 security update

[Multipart message — attachments visible in raw view] — view raw

This post concerns:

Debian Security Advisory DSA-3796-1 (appended below)

The package involved is apache2.

I have two "live" internet webservers, one an uptodate jessie, 
the other a long-maintained wheezy. The jessie machine upgraded 
easily to the new apache2 packages, but apt on my wheezy does 
not find any to install.

This line is in my sources.list:

http://security.debian.org/ wheezy/updates main

The above-noted Advisory (see below) only mentions new apache2 
security upgrades for jessie, stretch and sid. May I safely 
assume that in fact there is no update to be applied for apache2 
running in wheezy?

Thanks

Package        : apache2
CVE ID         : CVE-2016-0736 CVE-2016-2161 CVE-2016-8743

Several vulnerabilities were discovered in the Apache2 HTTP server.

CVE-2016-0736

   RedTeam Pentesting GmbH discovered that mod_session_crypto was
   vulnerable to padding oracle attacks, which could allow an attacker
   to guess the session cookie.

CVE-2016-2161

   Maksim Malyutin discovered that malicious input to mod_auth_digest
   could cause the server to crash, causing a denial of service.

CVE-2016-8743

   David Dennerline, of IBM Security's X-Force Researchers, and Régis
   Leroy discovered problems in the way Apache handled a broad pattern
   of unusual whitespace patterns in HTTP requests. In some
   configurations, this could lead to response splitting or cache
   pollution vulnerabilities.  To fix these issues, this update makes
   Apache httpd be more strict in what HTTP requests it accepts.

   If this causes problems with non-conforming clients, some checks can
   be relaxed by adding the new directive "HttpProtocolOptions unsafe"
   to the configuration.

This update also fixes the issue where mod_reqtimeout was not enabled
by default on new installations.

For the stable distribution (jessie), these problems have been fixed in
version 2.4.10-10+deb8u8.

For the testing (stretch) and unstable (sid) distributions, these
problems have been fixed in version 2.4.25-1.

We recommend that you upgrade your apache2 packages.

No, the version in wheezy is probably also affected. However,
wheezy is now supported by the Long Term Support project, and
you need to make changes to get those packages.

 https://wiki.debian.org/LTS/Using

LTS has very limited resources.

You should consider upgrading to jessie.

THANK YOU!

I'm trying desperately to get out of the "live internet server" 
business. Obviously I no longer have any business being out 
there.

OP might find the long thread on the debian-lts mailing list that
begins here informative (though I have not read it myself):

  Wheezy update of apache2?
  https://lists.debian.org/debian-lts/2016/12/msg00142.html

Hope this helps.
