Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Improper Authentication (CVE-ID: CVE-2023-2975)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in the AES-SIV cipher implementation when authenticating empty data entries via the EVP_EncryptUpdate() and EVP_CipherUpdate() functions. A remote attacker can bypass authentication process and impact application's integrity.
2) Resource management error (CVE-ID: CVE-2023-3446)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the DH_check(), DH_check_ex() and EVP_PKEY_param_check() function when processing a DH key or DH parameters. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
3) Resource management error (CVE-ID: CVE-2023-3817)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when checking the long DH keys. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
4) Resource management error (CVE-ID: CVE-2023-5678)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within DH_generate_key() and DH_check_pub_key() functions. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
5) State Issues (CVE-ID: CVE-2023-6129)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in POLY1305 MAC (message authentication code) implementation on PowerPC CPU based platforms if the CPU provides vector instructions. A remote attacker can perform a denial of service (DoS) attack.
6) Resource management error (CVE-ID: CVE-2023-6237)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the way the EVP_PKEY_public_check() function handles RSA public keys. A remote attacker can supply an RSA key obtained from an untrusted source and perform a denial of service (DoS) attack.
7) NULL pointer dereference (CVE-ID: CVE-2024-0727)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when processing fields in the PKCS12 certificate. A remote attacker can pass specially crafted certificate to the server and perform a denial of service (DoS) attack.
