Technical details
An integer overflow vulnerability exists in mat4_read_header() when computing buffer sizes from attacker-controlled rows, cols, channels, and frames fields in MAT4 file headers. The function multiplies these 32-bit fields together without overflow checks, leading to signed 64-bit integer overflow in sf_count_t arithmetic. This can cause denial of service via SIGILL trap (on sanitized builds) or out-of-bounds memory access via corrupted length calculations during subsequent file parsing.
