Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In Foxit Reader before 9.1 and Foxit PhantomPDF before 9.1, a flaw exists within the parsing of the BITMAPINFOHEADER record in BMP files. The issue results from the lack of proper validation of the biSize member, which can result in a heap based buffer overflow. An attacker can leverage this to execute code in the context of the current process.
