Summary
=======

The package nodejs-lts-erbium before version 12.22.7-1 is vulnerable to
multiple issues including arbitrary code execution, url request
injection and certificate verification bypass.

Resolution
==========

Upgrade to 12.22.7-1.

# pacman -Syu "nodejs-lts-erbium>=12.22.7-1"

The problems have been fixed upstream in version 12.22.7.

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.
