Summary
tesseract security update
Details

A commercial quality OCR engine originally developed at HP between 1985 and 1995. In 1995, this engine was among the top 3 evaluated by UNLV. It was open-sourced by HP and UNLV in 2005.

Security Fix(es):

Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata LSTM model component loaded through Tesseract's deserializer can cause an unchecked signed integer multiplication in Convolve::DeSerialize in src/lstm/convolve.cpp to wrap the convolution output-channel count, undersizing the forward-pass output buffer while writes use the unwrapped element count and causing a heap out-of-bounds write during OCR recognition. This issue is fixed in version 5.5.3.(CVE-2026-73066)

Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata model loaded through TessBaseAPI::Init can cause SquishedDawg::readsquisheddawg in src/dict/dawg.cpp to accept an unterminated forward-edge run, after which SquishedDawg::Load calls numforwardedges(0) and lastedge in src/dict/dawg.h reads beyond edges, causing a heap out-of-bounds read and process crash before image processing. This issue is fixed in version 5.5.3.(CVE-2026-73067)
