Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Deserialization of Untrusted Data (CVE-ID: CVE-2022-42003)

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

The vulnerability exists due to insecure input validation when processing serialized data when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. A remote attacker can pass specially crafted data to the application and cause a denial of service condition on the target system.


2) Out-of-bounds write (CVE-ID: CVE-2020-36518)

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

The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can trigger out-of-bounds write and cause a denial of service condition on the target system.


3) XML External Entity injection (CVE-ID: CVE-2020-25649)

The vulnerability allows a remote attacker to modify information on the system.

The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass a specially crafted XML code to the affected application and modify information on the system.


4) Resource exhaustion (CVE-ID: CVE-2022-42004)

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

The vulnerability exists due to application does not properly control usage of deeply nested arrays in BeanDeserializer._deserializeFromArray. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


5) Deserialization of Untrusted Data (CVE-ID: CVE-2021-46877)

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

The vulnerability exists due to insecure input validation when processing serialized JsonNode values. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

Note, the vulnerability affects JDK serialization only.
