VUL-0: CVE-2020-28196: krb5: unbounded recursion via an ASN.1-encoded Kerberos message
Last modified: 2020-12-18 10:47:02 UTC
CVE-2020-28196 MIT Kerberos 5 (aka krb5) before 1.17.2 and 1.18.x before 1.18.3 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.

looks to me like only these codestreams are affected: - SUSE:SLE-12-SP2:Update/krb5 - SUSE:SLE-15:Update/krb5 - SUSE:SLE-15-SP1:Update/krb5 @Samuel: could you have a look too please and confirm that 1.6.3 is not affected?
