Package : libgoogle-gson-java
CVE ID : CVE-2022-25647
Debian Bug : 1010670

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 de-
serialization 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.
