Security database references:
In Mitre's CVE dictionary: CVE-2010-0408, CVE-2010-0434.
More information:

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.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
