Echo: tesseract: security update to 5.5.0-1+e8

medium Tenable Self-Hosted Container Security Plugin ID 478151

Description

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

 - Tesseract is an open source OCR engine. From 5.4.0 until 5.5.4, AppendLinePolygon in
 src/api/pagerenderer.cpp destroys the caller-owned right-to-left Pta accumulator while receiving it by
 value, leaving line_top_rtl_pts and line_bottom_rtl_pts dangling. On an upright Hebrew or Arabic page at
 the default PAGE XML level, POLYGONFLAG with a false skewed_flag enters the vulnerable calls, while
 LEVELFLAG greater than zero provides an alternative gate. The calls repeatedly read and free the stale
 object, causing a double free and use after free and allowing corrupted coordinates to reach
 RecalcPolygonline. This issue is fixed in version 5.5.4. (CVE-2026-119338)

Solution

Update the tesseract library and its related packages to version 5.5.0-1+e8 or later.
