Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
4) Cryptographic issues (CVE-ID: CVE-2023-5363)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error when processing key and initialisation vector lengths in EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and EVP_CipherInit_ex2() function. A remote attacker can gain access to potentially sensitive information.
The following ciphers and cipher modes are impacted: RC2, RC4, RC5, CCM, GCM and OCB.
