An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-52946 in the wild and no public exploit code.\n\nAffected product: Synology Drive Client. 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-2023-52946/ (Markdown: https://insights.sbomify.com/CVE-2023-52946/index.md)","id":"CVE-2023-52946","markdown":"https://insights.sbomify.com/CVE-2023-52946/index.md","name":"CVE-2023-52946","record":{"aliases":["GHSA-pfx6-gm2c-cw74"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology Drive Client","requires_auth":"none","summary":"Remote attackers can crash the Synology Drive Client via a buffer overflow in the vss service component.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"drive_client","vendor":"synology"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer copy without checking size of input ('Classic Buffer Overflow') vulnerability in vss service component in Synology Drive Client before 3.5.0-16084 allows remote attackers to overwrite trivial buffers and crash the client via unspecified vectors.","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 Synology Drive Client","id":"CVE-2023-52946","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":"Missing authorization in Synology Active Backup for Business Agent","id":"CVE-2023-52947"},"packages":[],"prev":{"headline":"Other in BeeDrive for desktop","id":"CVE-2023-52945"},"products":["Synology Drive Client"],"published":"2024-09-26","related":[{"cvss_score":7.8,"headline":"Other in Synology Drive Client","id":"CVE-2022-49038","kev_date_added":null,"published":"2024-09-26"},{"cvss_score":6.7,"headline":"Memory corruption in Synology Drive Client","id":"CVE-2022-49039","kev_date_added":null,"published":"2024-09-26"},{"cvss_score":6.5,"headline":"Information disclosure in Synology Drive Client","id":"CVE-2022-49037","kev_date_added":null,"published":"2024-09-26"},{"cvss_score":4.4,"headline":"Memory corruption in Synology Drive Client","id":"CVE-2022-49040","kev_date_added":null,"published":"2024-09-26"},{"cvss_score":4.4,"headline":"Memory corruption in Synology Drive Client","id":"CVE-2022-49041","kev_date_added":null,"published":"2024-09-26"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-26","vendors":["Synology"]},"summary":"Remote attackers can crash the Synology Drive Client via a buffer overflow in the vss service component.","url":"https://insights.sbomify.com/CVE-2023-52946/"}
