Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2022-41724)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources in crypto/tls when handling large TLS handshake records. A remote attacker can send specially crafted data to the application and perform a denial of service (DoS) attack.
The vulnerability affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert).
2) Resource exhaustion (CVE-ID: CVE-2022-41725)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper control over internal resources in net/http and mime/multipart. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Incorrect calculation (CVE-ID: CVE-2023-24532)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the ScalarMult and ScalarBaseMult methods of the P256 Curve may return an incorrect result if called with some specific unreduced scalars.
4) Infinite loop (CVE-ID: CVE-2023-24537)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when calling any of the Parse functions on Go source code which contains //line directives with very large line numbers. A remote attacker can consume all available system resources and cause denial of service conditions.
