Description
A vulnerability was identified in Axiomatic Bento4 up to 1.6.0-641. Affected is the function AP4_BitReader::SkipBits of the file Ap4Dac4Atom.cpp of the component DSI v1 Parser. Such manipulation of the argument n_presentations leads to heap-based buffer overflow. The attack needs to be performed locally. The exploit is publicly available and might be used. 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 allows local authenticated attackers to cause a denial of service or potentially corrupt memory via the AP4_BitReader::SkipBits function in the DSI v1 Parser component when processing a maliciously crafted n_presentations argument. Public exploit code is available; vendor has not responded to early disclosure.
