Echo: tesseract: security update to 5.5.0-1+e5

medium Tenable Cloud Security Plugin ID 474802

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 model loaded through
 TessBaseAPI::Init can cause SquishedDawg::read_squished_dawg in src/dict/dawg.cpp to accept an
 unterminated forward-edge run, after which SquishedDawg::Load calls num_forward_edges(0) and last_edge in
 src/dict/dawg.h reads beyond edges_, causing a heap out-of-bounds read and process crash before image
 processing. This issue is fixed in version 5.5.3. (CVE-2026-73067)

Solution

Update the tesseract library and its related packages to version 5.5.0-1+e5 or later.
