An issue, also known as DW201703-006, was discovered in libdwarf 2017-03-21. A heap-based buffer over-read in dwarf_formsdata() is due to a failure to check a pointer for being in bounds (in a few places in this function) and a failure in a check in dwarf_attr_list().

An issue, also known as DW201703-002, was discovered in libdwarf 2017-03-21. In _dwarf_decode_s_leb128_chk() a byte pointer was dereferenced just before it was checked for being in bounds, leading to a heap-based buffer over-read.
