A double-free vulnerability was found in libdwarf. In a multiply-corrupted DWARF object, libdwarf may try to dealloc(free) an allocation twice, potentially causing unpredictable and various results.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
