+	  <p>An out-of-bounds read vulnerability exists in the way 7-Zip
+	  handles Universal Disk Format (UDF) files.</p>
+	  <p>Central to 7-Zip’s processing of UDF files is the
+	  CInArchive::ReadFileItem method. Because volumes can have more than
+	  one partition map, their objects are kept in an object vector. To
+	  start looking for an item, this method tries to reference the proper
+	  object using the partition map’s object vector and the "PartitionRef"
+	  field from the Long Allocation Descriptor. Lack of checking whether
+	  the "PartitionRef" field is bigger than the available amount of
+	  partition map objects causes a read out-of-bounds and can lead, in
+	  some circumstances, to arbitrary code execution.</p>
