finish_stab in stabs.c in GNU Binutils 2.30 allows attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-of-bounds write of 8 bytes. This can occur during execution of objdump.
The product writes data past the end, or before the beginning, of the intended buffer.
