[VIM] CVE-2007-1375 additional vector?

[security curmudgeon]

http://cve.mitre.org/cgi-bin/cvename.cgi?name=2007-1375

Integer overflow in the substr_compare function in PHP 5.2.1 and earlier 
allows context-dependent attackers to read sensitive memory via a large 
value in the length argument, a different vulnerability than 
CVE-2006-1991.

This is based on MOPB-14-2007 which covers substr_compare. The PHP 
changelog however, says:

  - Fixed substr_compare and substr_count information leak (MOPB-14 by
    Stefan Esser) (Stas, Ilia)


So the mention of substr_count is new and would be a new vector.
