MEDIUM 5.5EPSS 0.18%

Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

GPAC MP4Box v2.4 was discovered to contain a floating point exception in the gf_parse_lfrac function (utils/error.c). Processing a crafted MP4 file containing a zero-denominator fraction string causes gf_parse_lfrac() to divide by zero, terminating the process with SIGFPE.
