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-2026-55645 in the wild and no public exploit code.\n\nAffected product: neutrinolabs xrdp. 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-2026-55645/ (Markdown: https://insights.sbomify.com/CVE-2026-55645/index.md)","id":"CVE-2026-55645","markdown":"https://insights.sbomify.com/CVE-2026-55645/index.md","name":"CVE-2026-55645","record":{"aliases":["DEBIAN-CVE-2026-55645","GHSA-3m4m-h22g-c7xx","UBUNTU-CVE-2026-55645"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"RDP server","requires_auth":"none","summary":"A remote unauthenticated attacker can cause a denial of service by sending a crafted RDP packet that triggers an out-of-bounds read in xrdp.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xrdp","vendor":"neutrinolabs"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"xrdp is an open source RDP server. Versions 0.10.6 and prior contain a vulnerability concerning the processing of Client Control PDUs. During the RDP connection sequence, the parser does not perform sufficient length validation before reading specific data fields from the network stream. A remote, unauthenticated attacker could potentially exploit this flaw by sending a specially crafted, truncated Client Control PDU. Due to missing bounds checks, the xrdp process may perform out-of-bounds memory reads, which can result in the termination of the service (Denial of Service). However, since xrdp forks a new process for each connection by default, an out-of-bounds read causing a process crash is unlikely to bring down the entire xrdp service.This issue has been fixed in version 0.10.6.1.","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":"xrdp: Out-of-bounds read in Client Control PDU processing (xrdp_rdp_process_data_control)","id":"CVE-2026-55645","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"vLLM speech-to-text endpoints allocate full upload before enforcing the audio file-size limit","id":"CVE-2026-55646"},"packages":[],"prev":{"headline":"Element X iOS: io.element.call deeplink allows attacker-controlled HTTPS origin and may grant mic/camera to that origin","id":"CVE-2026-55644"},"products":["xrdp"],"published":"2026-07-20","related":[{"cvss_score":9.8,"headline":"xrdp: lib_palette_update Heap Buffer Overflow \u0026 RCE","id":"CVE-2026-41252","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":9.3,"headline":"xrdp: RDP MAC signature (dataSignature) never verified on receive — integrity bypass in non-TLS mode","id":"CVE-2026-32105","kev_date_added":null,"published":"2026-04-17"},{"cvss_score":8.8,"headline":"xrdp: Channel Data Forwarding Fixed-Size Buffer Overflow","id":"CVE-2026-44178","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":8.8,"headline":"xrdp: Fail-open privilege drop in sesexec — child processes may execute as root if setuid fails","id":"CVE-2026-32107","kev_date_added":null,"published":"2026-04-17"},{"cvss_score":8.7,"headline":"xrdp: Pre-authentication out-of-bounds reads in channel parsers","id":"CVE-2026-33689","kev_date_added":null,"published":"2026-04-17"},{"cvss_score":8.7,"headline":"xrdp: Heap buffer overflow in EGFX channel","id":"CVE-2026-35512","kev_date_added":null,"published":"2026-04-17"},{"cvss_score":8.2,"headline":"xrdp: lib_framebuffer_update Has Integer Overflow Heap Info Leak \u0026 ASLR Bypass","id":"CVE-2026-41521","kev_date_added":null,"published":"2026-07-20"}],"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":"2026-07-21","vendors":["neutrinolabs"]},"summary":"A remote unauthenticated attacker can cause a denial of service by sending a crafted RDP packet that triggers an out-of-bounds read in xrdp.","url":"https://insights.sbomify.com/CVE-2026-55645/"}
