CVE-2019-11037
In PHP imagick extension in versions between 3.3.0 and 3.4.4, writing to an array of values in ImagickKernel::fromMatrix() function did not check that the address will be within the allocated array.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.97%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
