1) NULL pointer dereference (CVE-ID: CVE-2023-28484)

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

The vulnerability exists due to a NULL pointer dereference error in xmlSchemaFixupComplexType. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


2) Error Handling (CVE-ID: CVE-2023-23931)

The vulnerability allows an attacker to misuse Python API.

The vulnerability exists due to a soundness bug within the Cipher.update_into function, which can allow immutable objects (such as bytes) to be mutated. A malicious programmer can misuse Python API to introduce unexpected behavior into the application.


3) Resource exhaustion (CVE-ID: CVE-2022-45061)

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

The vulnerability exists due to usage of an unnecessary quadratic algorithm in one path when processing some inputs to the IDNA (RFC 3490) decoder. A remote attacker can pass a specially crafted name to he decoder, trigger resource excessive CPU consumption and perform a denial of service (DoS) attack.
