Arbitrary file reading via OCRLanguage traversal
Published Jul 3, 2024 · Updated Aug 2, 2024
Path traversal in Artifex Software Ghostscript before 10.03.1 allows attackers to read arbitrary files through OCRLanguage. The OCR device passes a traversing OCRLanguage value to Tesseract, which loads an attacker-supplied traineddata file whose user_patterns_file and debug_file settings copy chosen file contents into error output. Exploitation requires a build with Tesseract OCR devices and also permits error-prefixed output to be written to a chosen path.
