Description
GNU Binutils 2.28 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file, related to the byte_get_little_endian function in elfcomm.c, the get_unwind_section_word function in readelf.c, and ARM unwind information that contains invalid word offsets.
