CVE-2026-88053

Tesseract OCR engine (version 5.5.3 and earlier) is vulnerable to a heap out-of-bounds write in Classify::ReadIntTemplates (src/classify/intproto.cpp). The function reads NumClassPruners, NumClasses, and NumProtoSets from the TESSDATA_INTTEMP component of a crafted .traineddata file and uses them...

CVE-2026-88053: Out-of-bounds Write

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Classify::ReadIntTemplates in src/classify/intproto.cpp reads NumClassPruners, NumClasses, and NumProtoSets from the TESSDATAINTTEMP component of a crafted .traineddata file and uses those values as loop bounds without validati...

CVE-2026-88047: Stack-based Buffer Overflow

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Classify::ReadNormProtos in src/classify/normmatch.cpp parses the NORMPROTO component of a .traineddata file and uses std::istream::operatorchar to extract a whitespace-delimited token into a fixed 61-byte stack buffer without...
