Echo: tesseract: security update to 5.5.0-1+e7

high Tenable Cloud Security Plugin ID 476078

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, the callback form of
 GenericVector::read in src/ccutil/genericvector.h reads the independent int32 fields reserved and
 size_used_ from a .traineddata model without a cap or an invariant check. reserve(reserved) allocates the
 backing array, but the callback loop writes size_used_ elements. A crafted TESSDATA_INTTEMP component with
 version_id 4 or later can therefore set reserved to a small value and size_used_ to a large value when
 fontinfo_table_.read(fp, read_info) is called from src/classify/intproto.cpp, causing a heap out-of-bounds
 write of FontInfo structures, heap corruption, a crash, or potentially controlled corruption. No fixed
 release is available as of this review. (CVE-2026-88051)

Solution

Update the tesseract library and its related packages to version 5.5.0-1+e7 or later.
