See How to fix? for Debian:unstable relevant fixed versions and status.
In GNU Binutils 2.30, there's an integer overflow in the function load_specific_debug_section() in objdump.c, which results in malloc() with 0 size. A crafted ELF file allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
