CVE-2020-28196

CVE-2020-28196 affects MIT Kerberos 5 (krb5) prior to 1.17.2 and 1.18.x prior to 1.18.3. The vulnerability stems from unbounded recursion in the ASN.1 BER decoder (lib/krb5/asn.1/asn1_encode.c) due to no recursion limit for indefinite lengths. This can lead to denial of service due to resource ex...
