{"id":"CVE-2026-5441","state":"PUBLISHED","title":"Out-of-Bounds Read in DicomImageDecoder (PMSCT_RLE1 Decompression)","description":"An out-of-bounds read vulnerability exists in the `DecodePsmctRle1` function of `DicomImageDecoder.cpp`. The `PMSCT_RLE1` decompression routine, which decodes the proprietary Philips Compression format, does not properly validate escape markers placed near the end of the compressed data stream. A crafted sequence at the end of the buffer can cause the decoder to read beyond the allocated memory region and leak heap data into the rendered image output.","publishedAt":"2026-04-09T14:42:04.597Z","updatedAt":"2026-04-14T16:35:04.748Z","severity":{"score":7.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H","source":"CISA-ADP"},"assigner":"certcc","products":["Orthanc DICOM Server"],"affected":[{"vendor":"Orthanc","product":"DICOM Server","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.12.10","versionType":"custom"}]}],"references":["https://www.orthanc-server.com/","https://www.machinespirits.de/","https://kb.cert.org/vuls/id/536588"],"weaknesses":[],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/5xxx/CVE-2026-5441.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-5441","state":"PUBLISHED","datePublished":"2026-04-09T14:42:04.597Z","dateUpdated":"2026-04-14T16:35:04.748Z","assignerShortName":"certcc","assignerOrgId":"37e5125f-f79b-445b-8fad-9564f167944b","dateReserved":"2026-04-02T19:22:35.863Z"},"containers":{"cna":{"title":"Out-of-Bounds Read in DicomImageDecoder (PMSCT_RLE1 Decompression)","descriptions":[{"lang":"en","value":"An out-of-bounds read vulnerability exists in the `DecodePsmctRle1` function of `DicomImageDecoder.cpp`.
