USN-6735-1: Node.js vulnerabilities

Read Time:44 Second

It was discovered that Node.js incorrectly handled the use of invalid public
keys while creating an x509 certificate. If a user or an automated system were
tricked into opening a specially crafted input file, a remote attacker could
possibly use this issue to cause a denial of service. This issue only affected
Ubuntu 23.10. (CVE-2023-30588)

It was discovered that Node.js incorrectly handled the use of CRLF sequences to
delimit HTTP requests. If a user or an automated system were tricked into
