EUVDB-ID: #VU39082

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-8421

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The function coff_set_alignment_hook in coffcode.h in Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has a memory leak vulnerability which can cause memory exhaustion in objdump via a crafted PE file. Additional validation in dump_relocs_in_section in objdump.c can resolve this.
