Apache 2.2.x < 2.2.12 Multiple Vulnerabilities

Medium Nessus Plugin ID 40467

Synopsis

The remote web server may be affected by several issues.

Description

According to its banner, the version of Apache 2.2.x. running on the remote host is prior to 2.2.12. It is, therefore, affected by the following vulnerabilities :

- A heap-based buffer underwrite flaw exists in the function 'apr_strmatch_precompile()' in the bundled copy of the APR-util library, which could be triggered when parsing configuration data to crash the daemon.
(CVE-2009-0023)

- A flaw in the mod_proxy_ajp module in version 2.2.11 only may allow a remote attacker to obtain sensitive response data intended for a client that sent an earlier POST request with no request body.
(CVE-2009-1191)

- The server does not limit the use of directives in a .htaccess file as expected based on directives such as 'AllowOverride' and 'Options' in the configuration file, which could enable a local user to bypass security restrictions. (CVE-2009-1195)

- Failure to properly handle an amount of streamed data that exceeds the Content-Length value allows a remote attacker to force a proxy process to consume CPU time indefinitely when mod_proxy is used in a reverse proxy configuration. (CVE-2009-1890)

- Failure of mod_deflate to stop compressing a file when the associated network connection is closed may allow a remote attacker to consume large amounts of CPU if there is a large (>10 MB) file available that has mod_deflate enabled. (CVE-2009-1891)

- Using a specially crafted XML document with a large number of nested entities, a remote attacker may be able to consume an excessive amount of memory due to a flaw in the bundled expat XML parser used by the mod_dav and mod_dav_svn modules. (CVE-2009-1955)

- There is an off-by-one overflow in the function 'apr_brigade_vprintf()' in the bundled copy of the APR-util library in the way it handles a variable list of arguments, which could be leveraged on big-endian platforms to perform information disclosure or denial of service attacks. (CVE-2009-1956)

Note that Nessus has relied solely on the version in the Server response header and did not try to check for the issues themselves or even whether the affected modules are in use.

Solution

Upgrade to Apache version 2.2.12 or later. Alternatively, ensure that the affected modules / directives are not in use.
