CVE-2026-119341 Tesseract Memory Corruption and Denial of Service Vulnerability

Source agreement

Evidence confidence

Short explanation

In the open source OCR engine Tesseract, memory corruption and denial of service can occur because ReadAdaptedClass raw-reads pre-adapted template files without neutralizing pointer fields.

Why does it matter?

Attackers who can write file-controlled inputs can trigger memory corruption and denial of service.

What should be done?

  • Upgrade to version 5.5.4 or later
  • Follow vendor advisories

Show the technical text from the sources

Tesseract is an open source OCR engine. Prior to 5.5.4, ReadAdaptedClass in src/classify/adaptive.cpp raw-reads an ADAPT_CLASS_STRUCT from a pre-adapted-template .a file without neutralizing TempProtos and Config pointer fields before any destructor path. When the legacy engine is selected, classify_use_pre_adapted_templates is enabled, and an attacker can write the output-basename .a file, the success or rejection path can pass file-controlled pointers to ~ADAPT_CLASS_STRUCT and operator delete, causing memory corruption and denial of service. This issue is fixed in version 5.5.4.
