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::read_squished_dawg in src/dict/dawg.cpp to accept an unterminated forward-edge run, after which SquishedDawg::Load calls num_forward_edges(0) and last_edge in src/dict/dawg.h reads beyond edges_, causing a heap out-of-bounds read and process crash before image processing. This issue is fixed in version 5.5.3.

Summary		(es) Tesseract es un motor OCR de código abierto. Antes de la versión 5.5.3, un modelo .traineddata manipulado cargado a través de TessBaseAPI::Init puede hacer que SquishedDawg::read_squished_dawg en src/dict/dawg.cpp acepte una ejecución de borde delantero sin terminar, después de lo cual SquishedDawg::Load llama a num_forward_edges(0) y last_edge en src/dict/dawg.h lee más allá de edges_, causando una lectura fuera de límites en el heap y un fallo del proceso antes del procesamiento de la imagen. Este problema está solucionado en la versión 5.5.3.
