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.","state":0,"publishedAt":"2023-09-19T14:57:16.784+00:00","modifiedAt":"2024-09-24T18:56:15.507+00:00","affected":[{"ecosystem":"Vendor product","name":"blurhash-rs","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"whisperfish\",\n                    \"product\": \"blurhash-rs\",\n                    \"versions\": [\n                        {\n                            \"version\": \"= 0.1.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","score":8.6,"severity":"HIGH"}],"references":["https://github.com/whisperfish/blurhash-rs/security/advisories/GHSA-cxvp-82cq-57h2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-42447","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-42447","identifiers":["CVE-2023-42447"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
