CVE-2018-10921
Certain input files may trigger an integer overflow in ttembed input file processing.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Certain input files may trigger an integer overflow in ttembed input file processing. This overflow could potentially lead to corruption of the input file due to a lack of checking return codes of fgetc/fputc function calls.
