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. -- System Information: Debian Release: 4.0 APT prefers testing APT policy: (600, 'testing'), (500, 'unstable'), (500, 'stable') Architecture: amd64 (x86_64) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.18-2-amd64 Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Versions of packages apache2 depends on: ii apache2-mpm-prefork 2.2.3-3.1 Traditional model for Apache HTTPD apache2 recommends no packages. -- no debconf information

* 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.
