Vulnerability Title
Tesseract: Heap out-of-bounds write in LSTM Convolve layer via crafted .traineddata
Vulnerability Description
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.

Vulnerability Title
tesseract-ocr tesseract 缓冲区错误漏洞
Vulnerability Description
tesseract-ocr tesseract是tesseract-ocr组织的一款光学字符识别引擎。 tesseract-ocr tesseract 5.5.3之前版本存在缓冲区错误漏洞,该漏洞源于反序列化器加载特制的.traineddata LSTM模型组件时,Convolve::DeSerialize中存在未检查的带符号整数乘法,导致卷积输出通道数回绕,使前向传递输出缓冲区大小不足,写入时使用未回绕的元素计数,从而造成堆越界写入。
