In MP4v2 2.0.0, there is an integer underflow (with resultant memory corruption) when parsing MP4Atom in mp4atom.cpp. 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. In MP4v2 2.0.0, there is an integer overflow (with resultant memory corruption) when resizing MP4Array for the ftyp atom in mp4array.h. A dangling pointer is freed again in the destructor once an exception is triggered. This will be the file you will use to load the recordings to other systems.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.Ī double free exists in the MP4StringProperty class in mp4property.cpp in MP4v2 2.0.0.
In the folder, locate the recording by file type (MP4, AVI, FLV, MOV, MPEG, or VOB).Click on the name of the folder associated with the recording (in this example, it's "Amber's Test Recording").MAC: Click on the search icon in the top right hand corner of the desktop and search for the "Camtasia Studio" folder. WINDOWS: Click the start icon search for the "Camtasia Studio" folder.*Note: Your file will only be available for retrieval if you chose to "Produce" your recording when you originally created it.
