DEBIAN-CVE-2026-88051
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, the callback form of GenericVector::read in src/ccutil/genericvector.h reads the independent int32 fields reserved and sizeused from a .traineddata model without a cap or an invariant check. reservereserved allocates the backin...
CVE-2026-88053
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-2026-88054
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Plumbing::DeSerialize in src/lstm/plumbing.cpp rejects excessively large network stacks but accepts a zero-length stack for NTSERIES, NTPARALLEL, or NTREVERSED layers in a crafted .traineddata model. During LSTMRecognizer...
CVE-2026-88052
Tesseract is an open-source OCR engine. In versions 5.5.3 and earlier , the function UNICHARSET::load_via_fgets (in src/ccutil/unicharset.cpp) uses a declared unichar count as a loop bound and indexes into the unichars vector with an unchecked id. Because unichar_insert_backwards_compatible can l...
CVE-2026-88052 Tesseract: Heap out-of-bounds write in UNICHARSET::load_via_fgets via count/insert desynchronization
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, UNICHARSET::loadviafgets in src/ccutil/unicharset.cpp trusts the declared unichar count as a loop bound and uses id as an unchecked index into the unichars vector. unicharinsertbackwardscompatible can leave the vector unchanged...
CVE-2026-88051
Tesseract (open-source OCR engine) versions 5.5.3 and earlier contain a heap out-of-bounds write in the callback form of GenericVector::read (src/ccutil/genericvector.h). The function reads independent reserved and size_used_ int32 fields from a .traineddata model without a cap or invariant check...
CVE-2026-88051 Tesseract: Heap out-of-bounds write in GenericVector<T>::read due to independent reserved/size_used_ fields
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, the callback form of GenericVector::read in src/ccutil/genericvector.h reads the independent int32 fields reserved and sizeused from a .traineddata model without a cap or an invariant check. reservereserved allocates the backin...

CVE-2026-88049
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, prior .traineddata hardening added bounds checks to NetworkIO::CopyTimeStepGeneral and NetworkIO::Randomize in src/lstm/networkio.cpp but left NetworkIO::WriteTimeStepPart and NetworkIO::AddTimeStepPart unchecked. In...
CVE-2026-88049
A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine. A remote attacker could exploit a heap out-of-bounds write vulnerability in the LSTM::Forward function by providing a specially crafted input. This could lead to heap corruption, application crashes, or...
CVE-2026-88047
A flaw was found in Tesseract. This vulnerability, a stack buffer overflow, occurs when the OCR engine processes a specially crafted .traineddata file. An attacker can exploit this by providing a malformed input, leading to stack corruption, a denial of service DoS, and potentially allowing for...
CVE-2026-88049 Tesseract: Heap out-of-bounds write in LSTM::Forward via na_/gate-matrix dimension mismatch
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, prior .traineddata hardening added bounds checks to NetworkIO::CopyTimeStepGeneral and NetworkIO::Randomize in src/lstm/networkio.cpp but left NetworkIO::WriteTimeStepPart and NetworkIO::AddTimeStepPart unchecked. In...
CVE-2026-88047
Tesseract (open-source OCR engine), versions 5.5.3 and earlier , is affected by a stack buffer overflow in Classify::ReadNormProtos (src/classify/normmatch.cpp). The function parses the NORMPROTO component of a .traineddata file using std::istream::operator>>(char*) into a fixed 61-byte sta...
