USN-6692-1: Gson vulnerability

Releases

• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• libgoogle-gson-java - A Java serialization/deserialization library to convert Java Objects into JSON and back

Details

It was discovered that Gson incorrectly handled deserialization of untrusted
input data. If a user or an automated system were tricked into opening a
specially crafted input file, a remote attacker could possibly use this issue
to cause a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.04

• libgoogle-gson-java - 2.8.8-1ubuntu0.1

Ubuntu 20.04

• libgoogle-gson-java - 2.8.5-3+deb10u1build0.20.04.1

Ubuntu 18.04

• libgoogle-gson-java - 2.8.5-3~18.04.1~esm1
  Available with Ubuntu Pro

Ubuntu 16.04

• libgoogle-gson-java - 2.4-1ubuntu0.1~esm1
  Available with Ubuntu Pro

In general, a standard system update will make all the necessary changes.
