Detailed Description According to its banner, the version of Apache 2.2 installed on the remote host is older than 2.2.17. Such versions may be affected by several issues, including :

- Errors exist in the bundled expat library that may allow an attacker to crash the server when a buffer is over- read when parsing an XML document. (CVE-2009-3720 and CVE-2009-3560)

- An error exists in the 'apr_brigade_split_line' function in the bundled APR-util library. Carefully timed bytes in requests result in gradual memory increases leading to a denial of service. (CVE-2010-1623)

* Note: This check solely relied on the version number of the remote Web server to assess this vulnerability, so this might be a false positive.
