A local attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 18.04 LTS. (CVE-2019-12439) It was discovered that Bubblewrap incorrectly handled certain symlinks during sandbox setup. A local attacker could possibly use this issue to create files outside of the sandbox.
