libdwarf versions through 2.3.3 have a heap out-of-bounds read vulnerability in the dwarf_debug_addr_table() function. This flaw occurs because the function omits the table starting offset when validating the .debug_addr unit length. An attacker can exploit this by supplying a crafted object file with a non-zero offset table, causing dwarf_debug_addr_by_index() to read beyond the allocated heap buffer. This can lead to disclosure of adjacent heap memory or cause a crash in the consuming application.
