Heap-based buffer overflow in CoreFoundation in Mac OS X and OS X Server 10.4 through 10.4.3 allows remote attackers to execute arbitrary code via unknown attack vectors involving "validation of URLs."

The remote host is running Apple Mac OS X, but lacks Security Update 2005-009. This security update contains fixes for the following applications :
- Apache2
- Apache_mod_ssl
- CoreFoundation
- curl
- iodbcadmintool
- OpenSSL
- passwordserver
- Safari
- sudo
- syslog

The remote host appears to be running a version of Apache, an open source web server.  This version of Apache is vulnerable to a flaw in the way that it handles mod_ssl CRL verification callback.  In order for an attacker to exploit this flaw the attacker would need to find a server that was configured to use a malicious certificate revocation list (CRL). 

The remote host appears to be running a version of Apache, an open source web server.  This version of Apache is vulnerable to a flaw in the way that it handles malformed HTTP requests.  An attacker exploiting this flaw would be able to possibly corrupt cache memory or inject HTML requests to a vulnerable Apache server.  The vulnerability stems from a non-conformance to RFC 2616 that states that HTTP requests must not include both a 'Content-Length' and 'Transfer-Encoding' field.
