Overview

CVE-2017-17124 is a high-severity vulnerability. It was published on December 4, 2017 and has a CVSS 3.0 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.0 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

The _bfd_coff_read_string_table function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not properly validate the size of the external string table, which allows remote attackers to cause a denial of service (excessive memory consumption, or heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted COFF binary.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
