NVD Description

Note: Versions mentioned in the description apply only to the upstream tesseract package and not the tesseract package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

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, undersizing the forward-pass output buffer while writes use the unwrapped element count and causing a heap out-of-bounds write during OCR recognition. This issue is fixed in version 5.5.3.
