Technical details
A floating-point exception (FPE) occurs in the reframer_send_packet function when processing MP4 files with uninitialized or zero stream parameters (timescale, sample rate, or denominator values). The vulnerability is triggered by supplying a malformed MP4 file to MP4Box with operations like -split-size, causing an immediate crash via divide-by-zero. The fix sets a default denominator value of 1 to prevent the exception.
Affected products
