Summary
krb5 vulnerabilities
Details

It was discovered that Kerberos incorrectly handled certain S4U2Self requests. An attacker could possibly use this issue to cause a denial of service. This issue was only addressed in Ubuntu 16.04 ESM and Ubuntu 18.04 LTS. (CVE-2018-20217)

Greg Hudson discovered that Kerberos PAC implementation incorrectly handled certain parsing operations. A remote attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-42898)
