USN-6103-1: JSON Schema vulnerability

Releases

• Ubuntu 20.04 LTS
• Ubuntu 18.04 ESM

Packages

• node-json-schema - A vocabulary that allows you to validate, annotate, and manipulate JSON files

Details

It was discovered that JSON Schema incorrectly handled certain inputs. 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 exploit
JavaScript runtimes and cause a denial of service or execute arbitrary code.

Update instructions

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

Ubuntu 20.04

• node-json-schema - 0.2.3-1+deb10u1build0.20.04.1

Ubuntu 18.04

• node-json-schema - 0.2.3-1+deb10u1build0.18.04.1

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