RHEL 8 : tesseract (RHSA-2026:67832)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:67832 advisory. 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...

EUVD-2026-75630

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Classify::ReadIntTemplates in src/classify/intproto.cpp reads NumClassPruners, NumClasses, and NumProtoSets from the TESSDATAINTTEMP component of a crafted .traineddata file and uses those values as loop bounds without validati...

CVE-2026-88049

Tesseract (open-source OCR engine) versions 5.5.3 and earlier are affected by a heap out-of-bounds write in LSTM::Forward (src/lstm/lstm.cpp). Prior hardening added bounds checks to NetworkIO::CopyTimeStepGeneral and NetworkIO::Randomize but left NetworkIO::WriteTimeStepPart and NetworkIO::AddTim...

CVE-2026-73067

A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine. A remote attacker could exploit this vulnerability by providing a specially crafted .traineddata model. When this malicious model is loaded, it can cause the software to read beyond its allocated memory, leadi...

Linux Distros Unpatched Vulnerability : CVE-2026-73067

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata model loaded through TessBaseAPI::Init can cause SquishedDawg::readsquisheddawg i...

CVE-2026-73067

CVE-2026-73067 affects the Tesseract OCR engine. A crafted .traineddata model loaded via TessBaseAPI::Init can cause SquishedDawg::read_squished_dawg to accept an unterminated forward-edge run, leading to SquishedDawg::Load calling num_forward_edges(0) and last_edge reading beyond edges_, which t...

CVE-2026-73067 Tesseract: Heap OOB read in the DAWG loader

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 numforwardedges0 and lastedge in...

CVE-2026-73066

Tesseract prior to 5.5.3 is affected by a heap out-of-bounds write in LSTM Convolve via a crafted .traineddata loaded through the deserializer. The root cause is an unchecked signed integer multiplication that wraps the convolution output-channel count, undersizing the forward-pass output buffer ...

CVE-2026-73066 Tesseract: Heap out-of-bounds write in LSTM Convolve layer via crafted .traineddata

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,...
