Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) 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.
2) Resource exhaustion (CVE-ID: CVE-2023-33202)
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 internal resources when parsing OpenSSL PEM encoded streams containing X.509 certificates. A remote attacker can send ASN.1 data through the PEMParser to trigger resource exhaustion and perform a denial of service (DoS) attack.
3) XML External Entity injection (CVE-ID: CVE-2024-28757)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input when using external parsers via XML_ExternalEntityParserCreate. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
