Echo: tesseract: security update to 5.5.0-1+e3

high Tenable Cloud Security Plugin ID 473177

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, UNICHARSET::load_via_fgets in
 src/ccutil/unicharset.cpp trusts the declared unichar count as a loop bound and uses id as an unchecked
 index into the unichars vector. unichar_insert_backwards_compatible can leave the vector unchanged for an
 empty, duplicate, or already-encodable representation, causing id to become larger than unichars.size().
 Subsequent set_* calls and the write to unichars[id].properties.enabled then write UNICHAR_PROPERTIES
 beyond the vector during initialization in both the default LSTM and legacy engines, causing heap
 corruption, a crash, or potentially controlled corruption. No fixed release is available as of this
 review. (CVE-2026-88052)

Solution

Update the tesseract library and its related packages to version 5.5.0-1+e3 or later.
