It was discovered that Gson, a Java library that can be used to convert Java Objects into their JSON representations and vice versa, was vulnerable to a deserialization flaw. An application would de-serialize untrusted data without sufficiently verifying that the resulting data will be valid, letting the attacker to control the state or the flow of the execution. This can lead to a denial of service or even the execution of arbitrary code. For the stable distribution (bullseye), this problem has been fixed in version 2.8.6-1+deb11u1. We recommend that you upgrade your libgoogle-gson-java packages.
