Apache HTTP Server Vulnerability Advisory for Adobe Flash Media Server Customers
http://blogs.adobe.com/psirt/2010/03/apache_http_server_vulnerabili.html

An important vulnerability was recently identified in Apache HTTP Server version 2.2.14 and earlier (CVE-2010-0425: mod_isapi module unload flaw). The flaw in mod_isapi could result in an attempt to unload the ISAPI dll when encountering various error states. This could leave the callbacks in an undefined state and result in a segfault. On Windows platforms using mod_isapi, a remote attacker could send a malicious request to trigger this issue, and as win32 MPM runs only one process, this would result in a denial of service, and potentially allow arbitrary code execution. This vulnerability has been fixed in Apache httpd 2.2.15.
