CVE-2021-21848
25.08.2021, 19:15
An exploitable integer overflow vulnerability exists within the MPEG-4 decoding functionality of the GPAC Project on Advanced Content library v1.0.1. The library will actually reuse the parser for atoms with the stsz FOURCC code when parsing atoms that use the stz2 FOURCC code and can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. An attacker can convince a user to open a video to trigger this vulnerability.Enginsight

Common Weakness Enumeration
- CWE-680 - Integer Overflow to Buffer OverflowThe 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.
- CWE-119 - Improper Restriction of Operations within the Bounds of a Memory BufferThe software performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer.
