CVE-2017-14064

原文の説明

Ruby through 2.2.7, 2.3.x through 2.3.4, and 2.4.x through 2.4.1 can expose arbitrary memory during a JSON.generate call. The issues lies in using strdup in ext/json/ext/generator/generator.c, which will stop after encountering a '\0' byte, returning a pointer to a string of length zero, which is not the length stored in space_len.

影響を受けるソフトウェア

• Ruby ≤ 2.2.7= 2.3.3= 2.4.0= 2.3.1= 2.4.1= 2.3.4 完全一致
