Trellix Agent < 5.7.9 Heap-Based Overflow Vulnerability (SB10396)

medium Nessus Plugin ID 175110


A security management agent installed on the remote host is affected by multiple vulnerabilities.


The version of Trellix Agent, formerly McAfee Agent or McAfee Policy Orchestrator (ePO) Agent, installed on the remote host is prior to 5.7.9. It is, therefore, affected by a heap-based overflow vulnerability in TA 5.7.8 and earlier allows a remote user to alter the page heap in the macmnsvc process memory block, resulting in the service becoming unavailable. (CVE-2023-0977)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to McAfee Agent version 5.7.9 or later.
