Arch Linux Security Advisory ASA-202110-5 ========================================= Severity: High Date : 2021-10-21 CVE-ID : CVE-2021-22939 CVE-2021-22940 CVE-2021-22959 CVE-2021-22960 Package : nodejs-lts-fermium Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-2284 Summary ======= The package nodejs-lts-fermium before version 14.18.1-1 is vulnerable to multiple issues including arbitrary code execution, url request injection and certificate verification bypass. Resolution ========== Upgrade to 14.18.1-1. # pacman -Syu "nodejs-lts-fermium>=14.18.1-1" The problems have been fixed upstream in version 14.18.1. Workaround ========== None. Description =========== - CVE-2021-22939 (certificate verification bypass) If the Node.js https API in versions before 16.6.2, 14.17.5 and 12.22.5 was used incorrectly and "undefined" was in passed for the "rejectUnauthorized" parameter, no error was returned and connections to servers with an expired certificate would have been accepted. - CVE-2021-22940 (arbitrary code execution) Node.js before versions 16.6.2, 14.17.5 and 12.22.5 is vulnerable to a use after free attack where an attacker might be able to exploit memory corruption to change process behavior. The issue is a follow on to CVE-2021-22930 as the issue was not completely resolved in the fix for CVE-2021-22930. - CVE-2021-22959 (url request injection) A security issue has been found in Node.js before versions 16.11.1, 14.18.1 and 12.22.7. The http parser accepts requests with a space (SP) right after the header name before the colon. This can lead to HTTP Request Smuggling (HRS). - CVE-2021-22960 (url request injection) A security issue has been found in Node.js before versions 16.11.1, 14.18.1 and 12.22.7. The parser ignores chunk extensions when parsing the body of chunked requests. This leads to HTTP Request Smuggling (HRS) under certain conditions. Impact ====== Incorrect use of the https API could lead to expired certificates being accepted. Furthermore a remote attacker could execute arbitrary code or inject HTTP requests through crafted queries.
