Overview

Multiple race conditions in suexec in Apache HTTP Server (httpd) 2.2.3 between directory and file validation, and their usage, allow local users to gain privileges and execute arbitrary code by renaming directories or performing symlink attacks. NOTE: the researcher, who is reliable, claims that the vendor disputes the issue because "the attacks described rely on an insecure server configuration" in which the user "has write access to the document root."

Vendor Statements (disclaimer)

Official Statement from Red Hat (04/19/2007)

These attacks are reliant on an insecure configuration of the server - that the user the server runs as has write access to the document root. The suexec security model is not intented to protect against privilege escalation in such a configuration
