The vulnerability can only be exploited with 12-bit data precision for which the range of the sample data type exceeds the valid sample range, hence, an attacker could craft a 12-bit lossless JPEG image that contains out-of-range 12-bit samples. An application attempting to decompress such image using merged upsampling would lead to segmentation fault or buffer overflows, causing an application to crash."}], "lastModified": "2024-02-13T19:15:08.517", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:libjpeg-turbo:libjpeg-turbo:2.1.90:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B3DDE171-3648-4EA8-BD44-788B3FDAF61E"}], "operator": "OR"}]}], "sourceIdentifier": "secalert@redhat.com"}
