Echo: tesseract: security update to 5.5.0-1+e4

high Tenable Cloud Security Plugin ID 473169

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Tesseract is an open source OCR engine. In version 5.5.3 and earlier, FullyConnected::DeSerialize in
src/lstm/fullyconnected.cpp does not validate the deserialized layer scalars ni_ and no_ against the
weight-matrix dimensions. During FullyConnected::Forward, MatrixDotVector in src/lstm/weightmatrix.cpp
writes w.dim1() results into temp_line, which is sized from no_, and reads w.dim2() minus one inputs from
curr_input, which is sized from ni_. A crafted .traineddata NT_SOFTMAX layer can therefore use
inconsistent dimensions to cause a heap out-of-bounds write and read on the default LSTM engine, resulting
in heap corruption, a crash, information disclosure, or potentially controlled corruption. No fixed
release is available as of this review. (CVE-2026-88048)

Solution

Update the tesseract library and its related packages to version 5.5.0-1+e4 or later.
