Debian LTS Advisory DLA-3213-1 [email protected]

Package : krb5
Version : 1.17-3+deb10u5
CVE ID : CVE-2022-42898
Debian Bug : 1024267

It was discovered that there was a potential Denial of Service (DoS)
attack against krb5, a suite of tools implementing the Kerberos
authentication system. An integer overflow in PAC parsing could have
been exploited if a cross-realm entity acted maliciously.

For Debian 10 buster, this problem has been fixed in version
1.17-3+deb10u5.

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
