| Title | Bento4 <=1.6.0-641 Memory Corruption |
|---|
| Description | A heap-buffer-overflow vulnerability was found in AP4_Dac4Atom constructor in Ap4Dac4Atom.cpp. When parsing a crafted MP4 file with a dac4 atom containing insufficient payload, AP4_BitReader::ReadCache() reads beyond the heap-allocated buffer. This leads to out-of-bounds read (CWE-125), causing potential information disclosure or denial of service. |
