This PHP vulnerability is officially named CVE-2011-4885 . It's a unique identifier. Redhat's own internal ticket number for this one, for instance only, is at https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2011-4885 or https://bugzilla.redhat.com/show_bug.cgi?id=750547, the same ticket under both names. RH, again for example, has released an updated PHP kit at https://rhn.redhat.com/errata/RHSA-2012-0019.html.
But just go update your PHP installs. It's an apt-get upgrade and you're done. You should have this automated (based on your patch policy). And if you hand-compile your own stuff and spray files all over your system, well, you're probably used to watching ocert like a hawk and emerging things on 20 boxes at once as a hobby ;-)
