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.
