CVE-2006-4486
Integer overflow in memory allocation routines in PHP before 5.1.6, when running on a 64-bit system, allows context-dependent attackers to bypass the memory_limit restriction.
Does this matter?
Lower severity and a low EPSS score (2.36%). Track it; it rarely justifies an emergency change on its own.
