Description

This security bulletin contains information about 12 secuirty vulnerabilities.

1) Memory leak (CVE-ID: CVE-2024-36114)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak when handling untrusted input. A remote attacker can force the application to leak memory and perform denial of service attack.

2) Buffer overflow (CVE-ID: CVE-2024-36129)

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

The vulnerability exists due to a boundary error within the Zip/Decompression Bomb sent over HTTP or gRPC. A remote attacker can trigger memory corruption and cause a denial of service condition on the target system.

3) Out-of-bounds read (CVE-ID: CVE-2024-5535)

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

The vulnerability exists due to a boundary condition within the SSL_select_next_proto() function when using NPN. A remote attacker can send specially crafted data to the application, trigger an out-of-bounds read and perform a denial of service (DoS) attack.

4) Improper Certificate Validation (CVE-ID: CVE-2021-44531)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to insufficient validation of URI Subject Alternative Names. Node.js accepts arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type. A remote attacker can bypass name-constrained intermediates and perform spoofing attack.

5) Inefficient regular expression complexity (CVE-ID: CVE-2024-45296)

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

The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

6) Incorrect Regular Expression (CVE-ID: CVE-2024-4067)

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

The vulnerability occurs in `micromatch.braces()` in `index.js` because the pattern `.*` will greedily match anything. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

7) Not a vulnerability (CVE-ID: CVE-2024-6531)

The reported issue was reviewed and determined not to constitute a security vulnerability.

Original description:

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via an anchor element (<a>), when used for carousel navigation with a data-slide attribute. A remote attacker can execute arbitrary JavaScript code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

8) Resource exhaustion (CVE-ID: CVE-2024-26308)

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

The vulnerability exists due to application does not properly control consumption of memory when unpacking a broken Pack200 file. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

9) Infinite loop (CVE-ID: CVE-2024-25710)

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

The vulnerability exists due to infinite loop when processing a corrupt DUMP file. A remote attacker can consume all available system resources and cause denial of service conditions.

10) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2024-42459)

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

The vulnerability exists due to an error when handling EDDSA signatures. A remote attacker can bypass signature-based security checks.

11) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2024-42460)

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

The vulnerability exists due to an error when handling ECDSA signatures. A remote attacker can bypass signature-based security checks.

12) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2024-42461)

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

The vulnerability exists due to an error when handling BER-encoded ECDSA signatures. A remote attacker can bypass signature-based security checks.
