Greg Hudson discovered integer overflow flaws in the PAC parsing in krb5, the MIT implementation of Kerberos, which may result in remote code execution (in a KDC, kadmin, or GSS or Kerberos application server process), information exposure (to a cross-realm KDC acting maliciously), or denial of service (KDC or kadmind process crash). For the stable distribution (bullseye), this problem has been fixed in version 1.18.3-6+deb11u3. We recommend that you upgrade your krb5 packages. For the detailed security status of krb5 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/krb5
