Security database references:
In the Debian bugtracking system: Bug 1024267.
In Mitre's CVE dictionary: CVE-2022-42898.
More information:

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.
