Improper Restriction of Operations within the Bounds of a Memory Buffer
CVE-2022-1441
Summary
MP4Box is a component of GPAC, which is a widely-used third-party package on RPM Fusion. When MP4Box tries to parse a MP4 file, it calls the function 'diST_box_read()' to read from video. In this function, it allocates a buffer `str` with fixed length. However, content read from `bs` is controllable by user, so is the length, which causes a buffer overflow. This issue affects versions prior to 2.2.0.

CWE-119 - Buffer Overflow
Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
