CVE-2019-9025
An invalid multibyte string supplied as an argument to the mb_split() function in ext/mbstring/php_mbregex.c can cause PHP to execute memcpy() with a negative argument, which could read and write past buffers allocated for the data.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.06%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
