Detailsinfo

A vulnerability classified as critical has been found in MP4v2 2.0.0. This affects the function MP4Atom::factory of the file mp4atom.cpp. The manipulation as part of a MP4 File leads to a type conversion vulnerability. CWE is classifying the issue as CWE-704. The product does not correctly convert an object, resource, or structure from one type to a different type. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

MP4Atom::factory in mp4atom.cpp in MP4v2 2.0.0 incorrectly uses the MP4ItemAtom data type in a certain case where MP4DataAtom is required, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted MP4 file, because access to the data structure has different expectations about layout as a result of this type confusion.
