Name of the Vulnerable Software and Affected Versions
Tesseract versions prior to 5.5.3
Description
A heap out-of-bounds write can occur during OCR recognition when a crafted
.traineddata LSTM model component is loaded through the deserializer. This happens because an unchecked signed integer multiplication in the Convolve::DeSerialize() function within src/lstm/convolve.cpp can cause the convolution output-channel count to wrap. This results in an undersized forward-pass output buffer, while subsequent writes use the unwrapped element count, leading to memory corruption.Recommendations
Update Tesseract to version 5.5.3.
