CVE-2018-14379

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.

Updated libmp4v2 packages fix security vulnerabilities:

The libmp4v2 library through version 2.1.0 is vulnerable to an integer underflow when parsing an MP4Atom in mp4atom.cpp. An attacker could exploit this to cause a denial of service via crafted MP4 file (CVE-2018-14325).

The libmp4v2 library through version 2.1.0 is vulnerable to an integer overflow and resultant heap-based buffer overflow when resizing an MP4Array for the ftyp atom in mp4array.h. An attacker could exploit this to cause a denial of service via crafted MP4 file (CVE-2018-14326).

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 (CVE-2018-14379).

MP4NameFirstMatches in mp4util.cpp in MP4v2 2.0.0 mishandles substrings of atom names, leading to use of an inappropriate data type for associated atoms. The resulting type confusion can cause out-of-bounds memory access (CVE-2018-14403).

MP4Integer32Property::Read in atom_avcC.cpp in MP4v2 2.1.0 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted MP4 file (CVE-2018-14446).
