I'm forwarding this to oss-security just for the interest of documentation.

As far as we can tell, Bug #68665 has two completely unrelated bugs
and you are perhaps asking about CVE IDs for both of them.

First, there is an apprentice.c bug:

> I found an invalid free that will cause a crash/memory corruption in the
> master repo(git) of PHP:

>
http://git.php.net/?p=php-src.git;a=commit;h=a72cd07f2983dc43a6bb35209dc4687852e53c09

[ and in PHP 5.6

http://git.php.net/?p=php-src.git;a=commit;h=ef89ab2f99fbd9b7b714556d4f1f50644eb54191
]

Use CVE-2014-9426.


Then, there is a zend_language_scanner.c bug:

There is currently no CVE ID for this. The practice that we follow is
not the same for every piece of software. For example, in the past we
have assigned CVE IDs for vulnerabilities in FFmpeg that did not
affect any FFmpeg release. The rationale for this is that Google was
incorporating unreleased FFmpeg code into Chrome. In the case of PHP,
we do not know of (for example) current cases in which a Linux
distribution ships packages based on using the PHP master tree at an
arbitrary point in time. Also, we have not seen PHP maintainers
advertise that end users should individually use master. Accordingly,
for PHP, master seems to not directly correspond to a "product," and
at least some of the bugs are a reflection of the code being in an
indeterminate development state.
