Fix status not established

No structured fix or guidance is available here. Check the latest publisher advisory.

What this means

Tesseract OCR engine versions prior to 5.5.4 have a vulnerability where an attacker with write access can cause memory corruption and denial of service by passing file-controlled pointers to the destructor. The issue is fixed in version 5.5.4. Affected versions are those less than 5.5.3.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

Read the full publisher description

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.
