T1lib is a PostScript Type 1 font rasterization library with modest but concentrated vulnerability exposure centered in its single core product. The durable signal reflects the library's role parsing untrusted font data, with recurring weaknesses in memory-buffer handling and input validation that are characteristic of font processors operating on complex, variable-length structures. Public exploit code has accompanied disclosures affecting this library; defenders embedding T1lib should prioritize font-handling patches and consider constraining rasterization of untrusted sources. Live severity, exploitation, and exposure counts are shown alongside this summary.
