Common Vulnerabilities and Exposures assigned an identifier CVE-2010-1915 to the following vulnerability: The preg_quote function in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allows context-dependent attackers to obtain sensitive information (memory contents) by causing a userspace interruption of an internal function, related to the call time pass by reference feature, modification of ZVALs whose values are not updated in the associated local variables, and access of previously-freed memory.

Created attachment 433706 [details] Public MOPS-2010-017 reproducer

(In reply to comment #6) > This issue affects the versions of the php package, as shipped > with Red Hat Enterprise Linux 3, 4, and 5. The interruption described in the MOPS-2010-017 does not work in php versions in Red Hat Enterprise Linux 3, 4, and 5, as method __toString() is not called by zend_parse_parameters() in those versions. All MOPS interruption reproducers relying on __toString() being called from zend_parse_parameters() would fail on those PHP versions.
Closing this, see bug #617578, comment #3 for more detailed explanation. *** This bug has been marked as a duplicate of bug 169857 ***
