apache2 - several issues

Two issues have been found in the Apache HTTPD web server:

• CVE-2010-0408
  mod_proxy_ajp would return the wrong status code if it encountered an
  error, causing a backend server to be put into an error state until the
  retry timeout expired. A remote attacker could send malicious requests
  to trigger this issue, resulting in denial of service.
• CVE-2010-0434
  A flaw in the core subrequest process code was found, which could lead
  to a daemon crash (segfault) or disclosure of sensitive information
  if the headers of a subrequest were modified by modules such as
  mod_headers.

For the stable distribution (lenny), these problems have been fixed in
version 2.2.9-10+lenny7.

For the testing distribution (squeeze) and the unstable distribution
(sid), these problems have been fixed in version 2.2.15-1.

This advisory also provides updated apache2-mpm-itk packages which
have been recompiled against the new apache2 packages.

We recommend that you upgrade your apache2 and apache2-mpm-itk packages.
