February 2020 Security Releases
Updates are now available for all active Node.js release lines for the following issues.
Affected Node.js versions can be exploited to perform HTTP desync attacks and deliver malicious payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the underlying system.
Reported by Ethan Rubinson, a software engineer at eBay.
Optional whitespace should be trimmed from HTTP header values. Its presence may allow attackers to bypass security checks based on HTTP header values.
Reported by Alyssa Wilk from Google.
Remotely trigger an assertion on a TLS server with a malformed certificate string (High) (CVE-2019-15604)
Connecting to a NodeJS TLS server with a client certificate that has a type 19 string in its subjectAltName will crash the TLS server if it tries to read the peer certificate.
Reported by Rogier Schouten and Melvin Groenhoff.
Increase the strictness of HTTP header parsing. There are no known vulnerabilities addressed, but lax HTTP parsing has historically been a source of problems. Some commonly used sites are known to generate invalid HTTP headers, a
--insecure-http-parser CLI option or
insecureHTTPParser http option can be used if necessary for interoperability, but is not recommended.
The Node.js project will release new versions of all supported release lines on or shortly after Tuesday, February 4th, 2020.
One Critical severity and two High severity issues will be fixed. The release also includes stricter HTTP parsing.
All supported versions (10.x, 12.x, and 13.x) of Node.js are vulnerable.
Releases will be available at, or shortly after, Tuesday, February 4th, 2020.
