ASA-202101-15: nodejs-lts-fermium: multiple issues

Arch Linux Security Advisory ASA-202101-15
=========================================
Severity: High
Date : 2021-01-12
CVE-ID : CVE-2020-8265 CVE-2020-8287
Package : nodejs-lts-fermium
Type : multiple issues
Remote : No
Link :   https://security.archlinux.org/AVG-1401

Summary
======
The package nodejs-lts-fermium before version 14.15.4-1 is vulnerable
to multiple issues including arbitrary code execution and url request
injection.

Resolution
=========
Upgrade to 14.15.4-1.

# pacman -Syu "nodejs-lts-fermium>.15.4-1"

The problems have been fixed upstream in version 14.15.4.

Workaround
=========
None.

Description
==========
- CVE-2020-8265 (arbitrary code execution)

The nodejs release lines 15.x, 14.x, 12.x and 10.x are vulnerable to a
use-after-free bug in its TLS implementation. When writing to a TLS
enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite
with a freshly allocated WriteWrap object as first argument. If the
DoWrite method does not return an error, this object is passed back to
the caller as part of a StreamWriteResult structure. This may be
exploited to corrupt memory leading to a Denial of Service or
potentially other exploits. The issue is fixed in nodejs versions
15.5.1, 14.15.4, 12.20.1 and 10.23.1.

- CVE-2020-8287 (url request injection)

The nodejs release lines 15.x, 14.x, 12.x and 10.x allow two copies of
a header field in an HTTP request. For example, two Transfer-Encoding
header fields. In this case Node.js identifies the first header field
and ignores the second. This can lead to HTTP Request Smuggling. The
issue is fixed in nodejs versions 15.5.1, 14.15.4, 12.20.1 and 10.23.1.

Impact
=====
A malicious user could achieve data exfiltration through HTTP headers
or execute arbitrary code through poor API usage.
