Prior to 5.5.4, WeightMatrix::DeSerialize trusts a mode byte from a traineddata LSTM network and calls WeightMatrix::DeSerializeOld when kDoubleFlag is clear. In default FAST_FLOAT builds, DeSerializeOld invokes ASSERT_HOST instead of returning an error, so loading a crafted model through TessBaseAPI::Init terminates the process and causes denial of service. This issue is fixed in version 5.5.4.","cvssScore":5.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-20","CWE-617"],"vendors":[],"products":[],"references":[{"url":"https://github.com/tesseract-ocr/tesseract/commit/c053424327352b9d5180aa7540c1f9e67c64f27e","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/pull/4657","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/releases/tag/5.5.4","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-h9g4-frjx-6cj3","tags":[]}],"exploitRefs":[{"url":"https://github.com/tesseract-ocr/tesseract/commit/c053424327352b9d5180aa7540c1f9e67c64f27e","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/pull/4657","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/releases/tag/5.5.4","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-h9g4-frjx-6cj3","tags":[]}],"hasPoc":true,"ai":null}
