1) Out-of-bounds read (CVE-ID: CVE-2017-9038)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in GNU Binutils 2.28. A remote attacker can perform 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.
