    CVE-2020-28196

    Summary: Updated krb5 packages fix a security vulnerability

    Details: MIT Kerberos 5 (aka krb5) before 1.17.2 allows unbounded recursion via an ASN.1-encoded Kerberos message because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite lengths lacks a recursion limit (CVE-2020-28196).
