Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Resource management error (CVE-ID: CVE-2021-22569)

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. protobuf-java allowes the interleaving of com.google.protobuf.UnknownFieldSet fields in such a way that would be processed out of order. A small malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause frequent, repeated pauses. A remote attacker can trick the victim into passing specially crafted data to the application and perform a denial of service attack.


2) Improper input validation (CVE-ID: CVE-2022-1941)

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

The vulnerability exists due to improper input validation within the Connector/Python (Python) component in MySQL Connectors. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.


3) Input validation error (CVE-ID: CVE-2022-3171)

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

The vulnerability exists due to insufficient validation of user-supplied input containing multiple instances of non-repeated embedded messages with repeated or unknown fields. A remote attacker can cause objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses.
