CVE-2026-88054

A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine. A remote attacker could provide a specially crafted '.traineddata' model with a zero-length stack for certain internal layers. This would cause an empty-stack dereference during model loading, leading to a...

CVE-2026-88053

A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine. A local attacker could provide a specially crafted .traineddata file, which, when processed, could lead to a heap out-of-bounds write. This vulnerability occurs due to unvalidated counts used as loop bounds...

CVE-2026-88051

A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine. A heap out-of-bounds write vulnerability exists in the GenericVector::read function when processing a specially crafted .traineddata model. By manipulating the reserved and sizeused fields, a local attacker ca...
