Abstract: A compressed font file including compressed data is received. The compressed data is decompressed to generate decompressed data. An attempt to validate the decompressed data is made. Within the decompressed data, a predetermined pattern of invalid data corresponding to an element of a font file is detected. The font file is reconstructed by replacing at least some of the invalid data with the element.

Abstract translation: 接收包括压缩数据的压缩字体文件。 压缩数据被解压缩以生成解压缩数据。 尝试验证解压缩数据。 在解压缩数据中，检测与字体文件的元素对应的无效数据的预定模式。 通过用元素替换至少一些无效数据来重建字体文件。
