The Node_ValidatePtr function in corec/corec/node/node.c in mkclean 0.8.9 allows remote attackers to cause a denial of service (assert fault) via a crafted mkv file.
The KaxInternalBlock::ReadData function in libMatroska before 1.4.4 allows context-dependent attackers to obtain sensitive information from process heap memory via crafted EBML lacing, which triggers an invalid memory access.
The EbmlElement::ReadCodedSizeValue function in libEBML before 1.3.3 allows context-dependent attackers to obtain sensitive information from process heap memory via a crafted length value in an EBML id, which triggers an invalid memory access.
The EbmlUnicodeString::UpdateFromUTF8 function in libEBML before 1.3.3 allows context-dependent attackers to obtain sensitive information from process heap memory via a crafted UTF-8 string, which triggers an invalid memory access.
Use-after-free vulnerability in the EbmlMaster::Read function in libEBML before 1.3.3 allows context-dependent attackers to have unspecified impact via a "deeply nested element with infinite size" followed by another element of an upper level in an EBML document.
Buffer overflow in the Matroska demuxer (demuxers/demux_matroska.c) in xine-lib before 1.1.10.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a Matroska file with invalid frame sizes.
