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-2023-40576 in the wild and no public exploit code.\n\nAffected product: Freerdp Freerdp. 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-2023-40576/ (Markdown: https://insights.sbomify.com/CVE-2023-40576/index.md)","id":"CVE-2023-40576","markdown":"https://insights.sbomify.com/CVE-2023-40576/index.md","name":"CVE-2023-40576","record":{"aliases":["GHSA-x3x5-r7jm-5pq2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"RDP client library","requires_auth":"none","summary":"An out-of-bounds read in FreeRDP's RleDecompress function can cause application crashes, requiring users to upgrade to a patched version.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"freerdp","vendor":"freerdp"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Read in the `RleDecompress` function. This Out-Of-Bounds Read occurs because FreeRDP processes the `pbSrcBuffer` variable without checking if it contains data of sufficient length. Insufficient data in the `pbSrcBuffer` variable may cause errors or crashes. This issue has been addressed in version 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Out-Of-Bounds Read in FreeRDP","id":"CVE-2023-40576","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freerdp:freerdp","products":["freerdp:freerdp"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Alertmanager UI is vulnerable to stored XSS via the /api/v1/alerts endpoint","id":"CVE-2023-40577"},"packages":[],"prev":{"headline":"Out-Of-Bounds Read in FreeRDP","id":"CVE-2023-40575"},"products":["FreeRDP"],"published":"2023-08-31","related":[{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-37594","kev_date_added":null,"published":"2021-07-27"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-37595","kev_date_added":null,"published":"2021-07-27"},{"cvss_score":9.4,"headline":"FreeRDP Windows Client before 3.29.0 Heap Buffer Overflow via Cliprdr","id":"CVE-2026-67305","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 TLS Certificate Identity Validation Bypass","id":"CVE-2026-66402","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 HTTP Proxy Request Injection via Redirection","id":"CVE-2026-67289","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 WebSocket Ping Buffer Over-disclosure","id":"CVE-2026-67292","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 Improper Certificate Hostname Validation","id":"CVE-2026-67293","kev_date_added":null,"published":"2026-08-01"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2025-02-13","vendors":["FreeRDP"]},"summary":"An out-of-bounds read in FreeRDP's RleDecompress function can cause application crashes, requiring users to upgrade to a patched version.","url":"https://insights.sbomify.com/CVE-2023-40576/"}
