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...

CVE-2026-73066

Tesseract prior to 5.5.3 is affected by a heap out-of-bounds write in LSTM Convolve via a crafted .traineddata loaded through the deserializer. The root cause is an unchecked signed integer multiplication that wraps the convolution output-channel count, undersizing the forward-pass output buffer ...

CVE-2026-73066 Tesseract: Heap out-of-bounds write in LSTM Convolve layer via crafted .traineddata

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,...
