TencentOS Server 3: nodejs:18 (TSSA-2024:0108)
high Nessus Plugin ID 276343
Synopsis
The remote TencentOS Server 3 host is missing one or more security updates.Description
The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0108 advisory.Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:
CVE-2023-46809:
A flaw was found in Node.js. The privateDecrypt() API of the crypto library may allow a covert timing side-channel during PKCS#1 v1.5 padding error handling. This issue revealed significant timing differences in decryption for valid and invalid ciphertexts, which may allow a remote attacker to decrypt captured RSA ciphertexts or forge signatures, especially in scenarios involving API endpoints processing JSON Web Encryption messages.
CVE-2024-21892:
A flaw was found in Node.js. On Linux, Node.js ignores certain environment variables if an unprivileged user has set them while the process is running with elevated privileges, except for CAP_NET_BIND_SERVICE.
Due to a bug in the implementation of this exception, Node.js incorrectly applies this exception even when other capabilities have been set. This flaw allows unprivileged users to inject code that inherits the process's elevated privileges.
CVE-2024-22019:
A flaw was found in Node.js due to a lack of safeguards on chunk extension bytes. The server may read an unbounded number of bytes from a single connection, which can allow an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and a denial of service.
Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
