Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Covert Timing Channel (CVE-ID: CVE-2023-46809)
The vulnerability allows a remote attacker to perform Marvin attack.
The vulnerability exists due to a covert timing channel in the privateDecrypt() API of the crypto library. A remote attacker can perform a covert timing side-channel during PKCS#1 v1.5 padding error handling and decrypt captured RSA ciphertexts or forge signatures, especially in scenarios involving API endpoints processing Json Web Encryption messages.
2) Input validation error (CVE-ID: CVE-2024-22019)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when processing HTTP requests with chunked encoding. A remote attacker can send specially crafted HTTP request to the server and perform a denial of service (DoS) attack.
3) Improper handling of exceptional conditions (CVE-ID: CVE-2024-21892)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to the way certain environment variables are handled by Node.js on Linux. A local user can use a specially crafted environment variable to escalate privileges on the system.
4) Path traversal (CVE-ID: CVE-2024-21896)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in Buffer.prototype.utf8Write. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.
5) Path traversal (CVE-ID: CVE-2024-21891)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.
6) Inconsistency between implementation and documented design (CVE-ID: CVE-2024-21890)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to improper handling of wildcards in --allow-fs-read and --allow-fs-write. A remote attacker can gain access to sensitive information.
7) Improper Privilege Management (CVE-ID: CVE-2024-22017)
The vulnerability allows a local user to escalate privileges.
The vulnerability exists due to setuid() does not affect libuv's internal io_uring operations if initialized before the call to setuid(). A local user can escalate privileges on the system.
