Oracle Linux: CVE-2017-14064: ELSA-2018-0378: ruby security update (IMPORTANT) (Multiple Advisories)
Description
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. A buffer overflow vulnerability was found in the JSON extension of ruby. An attacker with the ability to pass a specially crafted JSON input to the extension could use this flaw to expose the interpreter's heap memory.
