{"id":"CVE-2023-40576","state":"PUBLISHED","title":"Out-Of-Bounds Read in FreeRDP","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.","publishedAt":"2023-08-31T21:35:38.155Z","updatedAt":"2025-02-13T17:08:33.700Z","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":">= 3.0.0-beta1, < 3.0.0-beta3","status":"affected"}]}],"references":["https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-x3x5-r7jm-5pq2","https://github.com/FreeRDP/FreeRDP/blob/5be5553e0da72178a4b94cc1ffbdace9ceb153e5/libfreerdp/codec/include/bitmap.c#L94-L113","https://security.gentoo.org/glsa/202401-16"],"weaknesses":["CWE-125"],"ingestedAt":"2026-10-29T20:06:17.512Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/40xxx/CVE-2023-40576.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-40576","state":"PUBLISHED","datePublished":"2023-08-31T21:35:38.155Z","dateUpdated":"2025-02-13T17:08:33.700Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-08-16T18:24:02.390Z"},"containers":{"cna":{"title":"Out-Of-Bounds Read in FreeRDP","descriptions":[{"lang":"en","value":"FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
