{"id":"CVE-2023-39351","state":"PUBLISHED","title":"FreeRDP Null Pointer Dereference leading denial of service","description":"FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions of FreeRDP are subject to a Null Pointer Dereference leading a crash in the RemoteFX (rfx) handling.  Inside the `rfx_process_message_tileset` function, the program allocates tiles using `rfx_allocate_tiles` for the number of numTiles. If the initialization process of tiles is not completed for various reasons, tiles will have a NULL pointer. Which may be accessed in further processing and would cause a program crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.","publishedAt":"2023-08-31T19:56:07.395Z","updatedAt":"2025-11-03T20:35:40.990Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["FreeRDP FreeRDP"],"affected":[{"vendor":"FreeRDP","product":"FreeRDP","versions":[{"version":"< 2.11.0","status":"affected"},{"version":">= 3.0.0-beta1, < 3.0.0-beta3","status":"affected"}]}],"references":["https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-q9x9-cqjc-rgwq","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/OH2ATH2BKDNKCJAU4WPPXK4SHLE3UJUV/","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/A6LLDAPEXRDJOM3PREDDD267SSNT77DP/","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IHMTGKCZXJPQOR5ZD2I4GPDNP2DKRXMF/","https://lists.debian.org/debian-lts-announce/2023/10/msg00008.html","https://security.gentoo.org/glsa/202401-16","https://lists.debian.org/debian-lts-announce/2025/02/msg00016.html"],"weaknesses":["CWE-476"],"ingestedAt":"2026-10-29T20:06:08.715Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/39xxx/CVE-2023-39351.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2023-39351","state":"PUBLISHED","datePublished":"2023-08-31T19:56:07.395Z","dateUpdated":"2025-11-03T20:35:40.990Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-07-28T13:26:46.477Z"},"containers":{"cna":{"title":"FreeRDP Null Pointer Dereference leading denial of service","descriptions":[{"lang":"en","value":"FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
