An exploitable integer truncation vulnerability exists within the MPEG-4 decoding functionality of the GPAC Project on Advanced Content library v1.0.1. The stri_box_read function is used when processing atoms using the stri FOURCC code. An attacker can convince a user to open a video to trigger this vulnerability.

Weakness

The product performs a calculation to determine how much memory to allocate, but an integer overflow can occur that causes less memory to be allocated than expected, leading to a buffer overflow.
