{"id":"CVE-2023-42447","state":"PUBLISHED","title":"blurhash panics on parsing crafted inputs","description":"blurhash-rs is a pure Rust implementation of Blurhash, software for encoding images into ASCII strings that can be turned into a gradient of colors representing the original image. In version 0.1.1, the blurhash parsing code may panic due to multiple panic-guarded out-of-bounds accesses on untrusted input. In a typical deployment, this may get triggered by feeding a maliciously crafted blurhashes over the network. These may include UTF-8 compliant strings containing multi-byte UTF-8 characters. A patch is available in version 0.2.0, which requires user intervention because of slight API churn. No known workarounds are available.","publishedAt":"2023-09-19T14:57:16.784Z","updatedAt":"2024-09-24T18:56:15.507Z","severity":{"score":8.6,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["whisperfish blurhash-rs"],"affected":[{"vendor":"whisperfish","product":"blurhash-rs","versions":[{"version":"= 0.1.1","status":"affected"}]}],"references":["https://github.com/whisperfish/blurhash-rs/security/advisories/GHSA-cxvp-82cq-57h2"],"weaknesses":["CWE-248","CWE-392","CWE-1284"],"ingestedAt":"2026-10-29T20:06:17.512Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/42xxx/CVE-2023-42447.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-42447","state":"PUBLISHED","datePublished":"2023-09-19T14:57:16.784Z","dateUpdated":"2024-09-24T18:56:15.507Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-09-08T20:57:45.573Z"},"containers":{"cna":{"title":"blurhash panics on parsing crafted inputs","descriptions":[{"lang":"en","value":"blurhash-rs is a pure Rust implementation of Blurhash, software for encoding images into ASCII strings that can be turned into a gradient of colors representing the original image.
