OESA-2021-1291 (CVE-2021-22918)

Vulnerability from osv_openeuler – Published: 2021-07-31 11:04 – Updated: 2026-08-06 11:04 – Source website

Summary

nodejs security update

Details

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Security Fix(es):

Node.js before 16.4.1, 14.17.2, 12.22.2 is vulnerable to an out-of-bounds read when uv__idna_toascii() is used to convert strings to ASCII. The pointer p is read and increased without checking whether it is beyond pe, with the latter holding a pointer to the end of the buffer. This can lead to information disclosures or crashes. This function can be triggered via uv_getaddrinfo().(CVE-2021-22918)

Severity

5.3 (Medium)
