NVD Description
Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by Alpine.
See How to fix? for Alpine:3.8 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.
