A Prototype Pollution vulnerability was found in lodash. Calling certain methods with untrusted JSON could lead to modifying objects up the prototype chain, including the global Object. A crafted JSON object passed to a vulnerable method could lead to denial of service or data injection, with various consequences.

A resource consumption vulnerability was found in nghttp2. This flaw allows an attacker to repeatedly construct an overly large HTTP/2 SETTINGS frame with a length of 14,400 bytes that causes excessive CPU usage, leading to a denial of service.

An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp.

A TLS Hostname verification bypass vulnerability exists in NodeJS. This flaw allows an attacker to bypass TLS Hostname verification when a TLS client reuses HTTPS sessions.

A flaw was found in nodejs. Calling napigetvaluestringlatin1(), napigetvaluestringutf8(), or napigetvaluestringutf16() with a non-NULL buf, and a bufsize of 0 will cause the entire string value to be written to buf, probably overrunning the length of the buffer.
