PERTAIN_TOReport

CVE-2022-38126: Memory leak in BFD DWARF abbreviation table handling

PERTAIN_TOProblem

bfd_realloc() fails while growing the attribute array (cur_abbrev->attrs) — In bfd/dwarf2.c, the function read_abbrevs(). Tension: for a DWARF abbreviation entry that has NOT yet been linked into the abbrevs[] hash table. Outcome: leaks heap memory.

PERTAIN_TOSolution

if (tmp == NULL) — tmp = (struct attr_abbrev *) bfd_realloc (cur_abbrev->attrs, amt);. Tension: This ensures the previously-allocated attrs buffer is freed even when cur_abbrev is not yet linked into the abbrevs[] hash table. Outcome: free (cur_abbrev->attrs); /* Fix: free old attrs before leaving */.
