Description
CVE-2026-119338 is a medium severity vulnerability in the Tesseract OCR engine versions 5.4.0 through 5.5.3. The flaw involves an out-of-bounds read and use-after-free in the AppendLinePolygon function, which mishandles right-to-left polygon accumulators on certain language pages like Hebrew or Arabic. This leads to double free and corrupted coordinate data. The issue is resolved in version 5.5.4.
