The Optical Character Recognition Project maintains a focused library for text extraction from images, and despite its narrow product scope, it serves as a foundational component across document-processing pipelines and accessibility applications where memory safety is critical. Its vulnerability exposure centers on low-level buffer-management and integer-arithmetic flaws—including improper memory bounds restrictions, out-of-bounds writes, integer overflow, and use-after-free conditions—that are characteristic of image-parsing code operating on untrusted input. Current severity, exploitation activity, and exposure counts are shown alongside this summary.
