Prior to 5.5.4, GENERIC_2D_ARRAY::DeSerializeSize in src/ccstruct/matrix.h reads matrix dimensions as signed int32_t values and compares them only with UINT16_MAX, allowing negative values to reach ResizeNoInit. Negative dimensions or a 65535 by 65535 product can create inconsistent allocation state and later out-of-bounds accesses while loading a crafted traineddata file, causing 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-190","CWE-681"],"vendors":[],"products":[],"references":[{"url":"https://github.com/tesseract-ocr/tesseract/commit/048e92378f1a34dcdaf94bc515c7552ac01f08ef","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/pull/4649","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/releases/tag/5.5.4","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-6xhq-wvww-6xfg","tags":[]}],"exploitRefs":[{"url":"https://github.com/tesseract-ocr/tesseract/commit/048e92378f1a34dcdaf94bc515c7552ac01f08ef","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/pull/4649","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/releases/tag/5.5.4","tags":[]},{"url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-6xhq-wvww-6xfg","tags":[]}],"hasPoc":true,"ai":null}
