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-2025-68118 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-2025-68118/ (Markdown: https://insights.sbomify.com/CVE-2025-68118/index.md)","id":"CVE-2025-68118","markdown":"https://insights.sbomify.com/CVE-2025-68118/index.md","name":"CVE-2025-68118","record":{"aliases":["GHSA-h78c-5cjx-jw6x","MINI-fgj3-5xqq-mwvj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"FreeRDP library","requires_auth":"none","summary":"An attacker can trigger a heap out-of-bounds read in FreeRDP via crafted input, potentially causing a client crash or exposing memory contents.","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":6.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.0, a vulnerability exists in FreeRDP’s certificate handling code on Windows platforms. The function `freerdp_certificate_data_hash_ uses` the Microsoft-specific `_snprintf` function to format certificate cache filenames without guaranteeing NUL termination when truncation occurs. According to Microsoft documentation, `_snprintf` does not append a terminating NUL byte if the formatted output exceeds the destination buffer size. If an attacker controls the hostname value (for example via server redirection or a crafted .rdp file), the resulting filename buffer may not be NUL-terminated. Subsequent string operations performed on this buffer may read beyond the allocated memory region, resulting in a heap-based out-of-bounds read. In default configurations, the connection is typically terminated before sensitive data can be meaningfully exposed, but unintended memory read or a client crash may still occur under certain conditions. Version 3.20.0 has a patch for the 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":"Potential Heap Out-of-Bounds Read in freerdp_certificate_data_hash_ via Unsafe _snprintf Usage","id":"CVE-2025-68118","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freerdp:freerdp","products":["freerdp:freerdp"],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Unexpected code execution when invoking toolchain in cmd/go","id":"CVE-2025-68119"},"packages":[],"prev":{"headline":"FileRise vulnerable to Cross-Site Scripting (XSS) in SVG File Handling","id":"CVE-2025-68116"},"products":["FreeRDP"],"published":"2025-12-17","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-18","vendors":["FreeRDP"]},"summary":"An attacker can trigger a heap out-of-bounds read in FreeRDP via crafted input, potentially causing a client crash or exposing memory contents.","url":"https://insights.sbomify.com/CVE-2025-68118/"}
