The documentation says: Lines that begin with the hash character "#" are considered comments, and are ignored. Comments may not be included on the same line as a configuration directive. > MITRE, does this qualify for a CVE? We can't make that decision without knowing the perspective of the upstream vendor. Because the upstream vendor has a process for assigning CVE IDs, we feel it would be simplest and best here to use that process, even if it is often not used in cases of publicly known vulnerabilities. See the security@...che.org address on the http://www.apache.org/security/committers.html page. It's their decision on how to proceed; possibilities include: - no CVE because the behavior with a # character is undefined - a single CVE for both because they intended "Comments may not be included" to only mean that a syntax error would be reported - a CVE only for mod_authz_host because they had actually wanted to support # comments for that one - -- CVE assignment team, MITRE CVE Numbering Authority M/S M300 202 Burlington Road, Bedford, MA 01730 USA [ PGP key available through http://cve.mitre.org/cve/request_id.html ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (SunOS) iQEcBAEBAgAGBQJVMCXsAAoJEKllVAevmvmsx1AH/ivWmhJm1RAzVk1H8bWQLfio aNk5M1NI4wV6iS4P3SpK5xd5oahAiQNb25bxFiqQTIVys+Q3dvhDroG6ZsiNxmKJ SaR2wRYIHsZmsmjkqxqyuH3KATtXsekzYF1kob0PhGvgL8BFbgqtQorZacYUZpjv yHMXMaSJrSLa8+yMRRcpoLvL7IKZdf8yvh2LUSIp6lvn2qtvNSk7UbB4I23ummiE 2bhUn0EhaVBqoDIOdbMi9uTGj25oJLdzHhHbNvfOxEbKS1hSTCRy5c/PbBxSslC8 J6a0OqCXUJ5zv7jixaLO/jlcJbdrM0YYlK+yZ6wc5W1K887TiJosKKr1Lgo38+U= =Wu5Y -----END PGP SIGNATURE-----
