Summary
An out of bounds write exists in FreeType versions 2.13.0 and below (newer versions of FreeType are not vulnerable) when attempting to parse font subglyph structures related to TrueType GX and variable font files. The vulnerable code assigns a signed short value to an unsigned long and then adds a static value causing it to wrap around and allocate too small of a heap buffer. The code then writes up to 6 signed long integers out of bounds relative to this buffer. This may result in arbitrary code execution. This vulnerability may have been exploited in the wild.

"value": "Existe una escritura fuera de los l\u00edmites en las versiones 2.13.0 y anteriores de FreeType al intentar analizar estructuras de subglifos de fuentes relacionadas con archivos de fuentes TrueType GX y variables. El c\u00f3digo vulnerable asigna un valor short con signo a un long sin signo y luego a\u00f1ade un valor est\u00e1tico, lo que provoca un bucle y asigna un b\u00fafer de mont\u00f3n demasiado peque\u00f1o. El c\u00f3digo escribe entonces hasta 6 enteros long con signo fuera de los l\u00edmites en relaci\u00f3n con este b\u00fafer. Esto puede provocar la ejecuci\u00f3n de c\u00f3digo arbitrario. Esta vulnerabilidad podr\u00eda haber sido explotada in situ."
