Package        : krb5
CVE ID         : CVE-2022-42898
Debian Bug     : 1024267

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.
