patch available.

  - suexec in Apache HTTP Server (httpd) 2.2.3 does not verify combinations of user and group IDs on the
    command line, which might allow local users to leverage other vulnerabilities to create arbitrary UID/GID
    owned files if /proc is mounted. 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. In addition, because this is dependent on other vulnerabilities,
    perhaps this is resultant and should not be included in CVE. (CVE-2007-1743)
