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-2026-88050 Tesseract: Out-of-bounds write in UnicharCompress via unvalidated recoder code values

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, RecodedCharID::DeSerialize in src/ccutil/unicharcompress.h validates length but accepts negative code values from a crafted .traineddata recoder component. UnicharCompress::ComputeCodeRange in src/ccutil/unicharcompress.cpp can...

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...

CVE-2026-88047 Tesseract: ReadNormProtos stack 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...

Linux Distros Unpatched Vulnerability : CVE-2026-88048

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Tesseract is an open source OCR engine. In version 5.5.3 and earlier, FullyConnected::DeSerialize in src/lstm/fullyconnected.cpp does not validate the...

PT-2026-89517

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 size used from a .traineddata model without a cap or an invariant check. reservereserved allocates the backi...

PT-2026-89518

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, UNICHARSET::load via fgets 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. unichar insert backwards compatible can leave the vector...

Linux Distros Unpatched Vulnerability : CVE-2026-73066

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata LSTM model component loaded through Tesseract's deserializer can cause an uncheck...

CVE-2026-73067

Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata model loaded through TessBaseAPI::Init can cause SquishedDawg::readsquisheddawg in src/dict/dawg.cpp to accept an unterminated forward-edge run, after which SquishedDawg::Load calls numforwardedges0 and lastedge in...

CVE-2026-73066

Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata LSTM model component loaded through Tesseract's deserializer can cause an unchecked signed integer multiplication in Convolve::DeSerialize in src/lstm/convolve.cpp to wrap the convolution output-channel count,...

Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata LSTM model component loaded through Tesseract's deserializer can cause an unchecked signed integer multiplication in Convolve::DeSerialize in src/lstm/convolve.cpp to wrap the convolution output-channel count,...

CVE-2026-73067 Tesseract: Heap OOB read in the DAWG loader

Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata model loaded through TessBaseAPI::Init can cause SquishedDawg::readsquisheddawg in src/dict/dawg.cpp to accept an unterminated forward-edge run, after which SquishedDawg::Load calls numforwardedges0 and lastedge in...

CVE-2026-73067

CVE-2026-73067 affects the Tesseract OCR engine. A crafted .traineddata model loaded via TessBaseAPI::Init can cause SquishedDawg::read_squished_dawg to accept an unterminated forward-edge run, leading to SquishedDawg::Load calling num_forward_edges(0) and last_edge reading beyond edges_, which t...
