Echo: tesseract: security update to 5.5.0-1+e1

medium Tenable Self-Hosted Container Security Plugin ID 462060

Description

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

 - 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. (CVE-2026-73066)

Solution

Update the tesseract library and its related packages to version 5.5.0-1+e1 or later.
