Fedora 34: FEDORA-2022-78090d2099 Medium: Node.js URI Handling Issues

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.

## 2022-01-10, Version 14.18.3 'Fermium' (LTS), @richardlau This is a security

release. ### Notable changes #### Improper handling of URI Subject Alternative

Names (Medium)(CVE-2021-44531) Accepting arbitrary Subject Alternative Name

(SAN) types, unless a PKI is specifically defined to use a particular SAN type,

can result in bypassing name-constrained intermediates. Node.js was accepting

URI SAN types, which PKIs are often not defined to use. Additionally, when a

protocol allows URI SANs, Node.js did not match the URI correctly. Versions of

Node.js with the fix for this disable the URI SAN type when checking a

certificate against a hostname. This behavior can be reverted through the

`--security-revert` command-line option. More details will be available at

[CVE-2021-44531](https://www.cve.org/CVERecord?id=CVE-2021-44531)

after publication. #### Certificate Verification Bypass via String Injection

(Medium)(CVE-2021-44532) Node.js converts SANs (Subject Alternative Names) to a

string format. It uses this string to check peer certificates against hostnames

when validating connections. The string format was subject to an injection

vulnerability when name constraints were used within a certificate chain,

allowing the bypass of these name constraints. Versions of Node.js with the fix

for this escape SANs containing the problematic characters in order to prevent

the injection. This behavior can be reverted through the `--security-revert`

command-line option. More details will be available at

[CVE-2021-44532](https://www.cve.org/CVERecord?id=CVE-2021-44532)

after publication. #### Incorrect handling of certificate subject and issuer

fields (Medium)(CVE-2021-44533) Node.js did not handle multi-value Relative

Distinguished Names correctly. Attackers could craft certificate subjects

containing a single-value Relative Distinguished Name that would be interpreted

as a multi-value Relative Distinguished Name, for example, in order to inject a

Common Name that would allow bypassing the certificate subject verification.

Affected versions of Node.js do not accept multi-value Relative Distinguished

Names and are thus not vulnerable to such attacks themselves. However, third-party code that uses node's ambiguous presentation of certificate subjects may

be vulnerable. More details will be available at

[CVE-2021-44533](https://www.cve.org/CVERecord?id=CVE-2021-44533)

after publication. #### Prototype pollution via `console.table` properties

(Low)(CVE-2022-21824) Due to the formatting logic of the `console.table()`

function it was not safe to allow user controlled input to be passed to the

`properties` parameter while simultaneously passing a plain object with at least

one property as the first parameter, which could be `__proto__`. The prototype

pollution has very limited control, in that it only allows an empty string to be

assigned numerical keys of the object prototype. Versions of Node.js with the

fix for this use a null protoype for the object these properties are being

assigned to. More details will be available at

[CVE-2022-21824](https://www.cve.org/CVERecord?id=CVE-2022-21824)

after publication. Thanks to Patrik Oldsberg (rugvip) for reporting this

vulnerability.
