Description

This security bulletin contains information about 1 vulnerability.

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

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

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.
