In Libav 12.3, a NULL pointer dereference (RIP points to zero) issue in ff_mpa_synth_filter_float in libavcodec/mpegaudiodsp_template.c can cause a segmentation fault (application crash) via a crafted mov file.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
