Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2023-44487)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.


2) Code Injection (CVE-ID: CVE-2023-39333)

The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The vulnerability exists due to improper input validation in an imported WebAssembly module when processing export names. A remote attacker can pass specially crafted export names to the application and execute arbitrary JavaScript code on the system.


3) Improper validation of integrity check value (CVE-ID: CVE-2023-38552)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to an error in the policy feature, which checks the integrity of a resource against a trusted manifest. An application can intercept the operation and return a forged checksum to node's policy implementation, thus effectively disabling the integrity check.
