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

medium Tenable Cloud Security Plugin ID 478157

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 5.5.4, GENERIC_2D_ARRAY::DeSerializeSize in
 src/ccstruct/matrix.h reads matrix dimensions as signed int32_t values and compares them only with
 UINT16_MAX, allowing negative values to reach ResizeNoInit. Negative dimensions or a 65535 by 65535
 product can create inconsistent allocation state and later out-of-bounds accesses while loading a crafted
 traineddata file, causing denial of service. This issue is fixed in version 5.5.4. (CVE-2026-119340)

Solution

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