CVE-2018-18327 — Trendmicro Antivirus For Mac 2017 security vulnerability

High CVSS 7.8

A KERedirect Untrusted Pointer Dereference Privilege Escalation vulnerability in Trend Micro Antivirus for Mac (Consumer) 7.0 (2017) and above could allow a local attacker to escalate privileges on vulnerable installations. The issue results from the lack of proper validation function on 0x6eDC offset user-supplied buffer. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
