It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-0977 in the wild and no public exploit code.\n\nAffected product: Trellix Agent. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-0977/ (Markdown: https://insights.sbomify.com/CVE-2023-0977/index.md)","id":"CVE-2023-0977","markdown":"https://insights.sbomify.com/CVE-2023-0977/index.md","name":"CVE-2023-0977","record":{"aliases":["GHSA-m928-3f5w-85qx"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Trellix Agent","requires_auth":"high_privilege","summary":"A remote attacker can cause a denial of service in Trellix Agent by triggering a heap-based overflow in the macmnsvc process.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"agent","vendor":"trellix"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A heap-based overflow vulnerability in Trellix Agent (Windows and Linux) version 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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in Trellix Agent","id":"CVE-2023-0977","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in Trellix Intelligent Sandbox","id":"CVE-2023-0978"},"packages":[],"prev":{"headline":"Command injection in Trellix Agent","id":"CVE-2023-0976"},"products":["Trellix Agent"],"published":"2023-04-03","related":[{"cvss_score":8.2,"headline":"Memory corruption in Trellix Agent (TA)","id":"CVE-2024-0213","kev_date_added":null,"published":"2024-01-09"},{"cvss_score":8.2,"headline":"Privilege escalation in Trellix Agent","id":"CVE-2023-0975","kev_date_added":null,"published":"2023-04-03"},{"cvss_score":6.7,"headline":"Privilege escalation in Trellix Agent","id":"CVE-2022-3859","kev_date_added":null,"published":"2022-11-30"},{"cvss_score":6.3,"headline":"Command injection in Trellix Agent","id":"CVE-2023-0976","kev_date_added":null,"published":"2023-06-07"},{"cvss_score":6.3,"headline":"Memory corruption in Trellix Agent","id":"CVE-2023-1388","kev_date_added":null,"published":"2023-06-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-11","vendors":["Trellix"]},"summary":"A remote attacker can cause a denial of service in Trellix Agent by triggering a heap-based overflow in the macmnsvc process.","url":"https://insights.sbomify.com/CVE-2023-0977/"}
