Package: apache2
Version: 2.2.3-3.1
Severity: critical
Justification: breaks the whole system
After a random time that goes from 5 minutes to days apache starts
forking a lot of processes, each using about 150m of VIRT and 20m
of RES memory. Most of the processes die and appear as <defunct> in
top or ps. After some tens of seconds the machine completely freeze
and should be rebooted. The console (the only time I was able to
have a look at it) has some kernel information about the oom-killer
killing apache2 but unfortunately this is happening to a remote
server and I don't have 24/24h access to it. Last time happened when
I was logged in and I was able to "killall apache2" and save the
box (this is how I understood what was happening.)
Right now I lowered the number of max clients from 150 to 25 but
this is not a definitive solution (for obvious reasons). If I can
do any test to provide better data just let me know.

Closes: 399776 421557 453630 453783
Changes:
apache2 (2.2.3-4+etch4) stable; urgency=low
.
* Fix various cross site scripting vulnerabilities with browsers that do not
conform to RFC 2616: Apache now adds explicit ContentType and Charset
headers to the output of various modules, even if AddDefaultCharset is
commented out. This includes directory indexes generated by mod_autoindex
and mod_proxy_ftp, which are now marked as iso-8859-1 by default.
(CVE-2007-4465, CVE-2008-0005, closes: #453783)
To allow to specify the character set for the directory indexes, the
Charset and Type IndexOptions and the ProxyFtpDirCharset directive have
been backported from 2.2.8.
If you use mod_autoindex and use UTF-8 for your filenames, you should add
Charset=UTF-8 to the IndexOptions line in /etc/apache2/apache2.conf .
If you use mod_proxy_ftp, the default charset can be set with the
ProxyFtpDirCharset directive in /etc/apache2/mods-available/proxy.conf .
ProxyFtpDirCharset can also be used inside <Proxy ...> </Proxy> blocks to
set the charset for specific servers.
* Reduce memory usage of chunk filter and ap_rwrite/ap_rflush
(Closes: #399776, #421557)
* More minor security fixes:
- XSS in mod_imagemap (CVE-2007-5000)
- XSS in mod_proxy_balancer's balancer manager (CVE-2007-6421)
- XSS in HTTP method in 413 error message (CVE-2007-6203)
- possible crash in mod_proxy_balancer's balancer manager (CVE-2007-6422)
* Fix mod_proxy_balancer configuration file parsing (closes: #453630).
* Don't ship NEWS.Debian with apache2-utils as it affects only the server.
Remove bogus reference to 2.2.3-5 from README.Debian, and add note about
MSIE SSL workaround.
