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

high Tenable Self-Hosted Container Security Plugin ID 474793

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, prior .traineddata hardening added
bounds checks to NetworkIO::CopyTimeStepGeneral and NetworkIO::Randomize in src/lstm/networkio.cpp but
left NetworkIO::WriteTimeStepPart and NetworkIO::AddTimeStepPart unchecked. In LSTM::Forward in
src/lstm/lstm.cpp, source_ is sized from the independently deserialized na_ field while the
WriteTimeStepPart count is ns_, which comes from the CI gate WeightMatrix dim1() value. A crafted NT_LSTM
layer can make ns_ much larger than na_, causing a heap out-of-bounds write during the first recognition
step on the default LSTM engine and resulting in heap corruption, a crash, or potentially controlled
corruption. No fixed release is available as of this review. (CVE-2026-88049)

Solution

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