4Description
A vulnerability was determined in Axiomatic Bento4 up to 1.6.0-641. This impacts the function AP4_BitReader::ReadCache of the file Ap4Dac4Atom.cpp of the component MP4 File Parser. This manipulation causes heap-based buffer overflow. The attack needs to be launched locally. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
Analysis
Heap-based buffer overflow in Axiomatic Bento4 up to version 1.6.0-641 affects the AP4_BitReader::ReadCache function in the MP4 file parser component, allowing local attackers with limited privileges to cause information disclosure, integrity violation, and denial of service. Publicly available exploit code exists, and the vendor has not yet responded to the early disclosure despite project notification through GitHub issue tracking.
