libdwarf 2016-10-21 allows context-dependent attackers to obtain sensitive information or cause a denial of service by using the "malformed dwarf file" approach, related to a "Heap Buffer Over-read" issue affecting the dwarf_util.c component, aka DW201611-006.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
