com.google.protobuf:protobuf-java is a Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data.
Affected versions of this package are vulnerable to Denial of Service (DoS). An issue in protobuf-java allowed 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.
Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.
Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.
One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.
When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.
Two common types of DoS vulnerabilities:
High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.
Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm
com.google.protobuf:protobuf-java to version 3.19.2, 3.18.2, 3.16.1 or higher.

junit:junit is an unit testing framework for Java
Affected versions of this package are vulnerable to Information Exposure. The JUnit4 test rule
TemporaryFolder contains a local information disclosure vulnerability. On Unix like systems, the system's temporary directory is shared between all users on that system. Because of this, when files and directories are written into this directory they are, by default, readable by other users on that same system.
Note: This vulnerability does not allow other users to overwrite the contents of these directories or files. This only affects Unix like systems.
junit:junit to version 4.13.1 or higher.
