node is vulnerable to Use-After-Free
80
High Risk
This Affects:
nodeTL;DR
Affected versions of Node.js are vulnerable to a heap-use-after-free due to improper handling of re-entrant HTTP/2 operations. A flaw in the interaction between nghttp2_session_mem_recv() and nghttp2_session_mem_send() allows memory to be accessed after it has been freed when processing specially crafted HTTP/2 frames. An attacker could exploit this vulnerability to cause a denial of service by crashing the application or, in certain circumstances, achieve arbitrary code execution.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
