| CVE ID: | CVE-2009-3586 |
| Affected Products: | CoreHTTP web server versions ≤ 0.5.3.1. |
| Class: | Improper Input Validation (CWE-20), Failure to Constrain Operations within the Bounds of a Memory Buffer (CWE-119) |
| Remote: | Yes |
| Discovered by: | Patroklos Argyroudis |
We have discovered a remotely exploitable “improper input validation” vulnerability in the CoreHTTP web server that leads to an off-by-one stack buffer overflow. The vulnerability can lead to denial of service attacks against the web server and potentially to the remote execution of arbitrary code with the privileges of the user running the server.

About four months ago I developed a reliable exploit for vulnerability
CVE-2008-3531, which is also addressed in the advisory
FreeBSD-SA-08:08.nmount. In this post I will use this vulnerability to provide an overview of the development process for FreeBSD kernel stack exploits.
CVE-2008-3531 is a kernel stack overflow vulnerability that affects FreeBSD versions 7.0-RELEASE and 7.0-STABLE, but not 7.1-RELEASE nor 7.1-STABLE as the CVE entry seems to suggest.
