CVE-2026-5235 Details
Description
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.
A heap-based buffer overflow vulnerability has been identified in Axiomatic Bento4 versions through 1.6.0-641. The issue arises in the MP4 file parser component, specifically within the AP4_Dac4Atom constructor of the Ap4Dac4Atom.cpp file. When a crafted MP4 file containing a dac4 atom with an insufficient payload size is parsed, the AP4_BitReader reads beyond the allocated heap buffer. This out-of-bounds read can lead to memory corruption, potentially allowing for information disclosure or causing a denial-of-service condition by crashing the application.
No known mitigation is available for this vulnerability.
