CVE-2020-28196

HIGH

MIT Kerberos <1.17.2, <1.18.x-1.18.3 - RCE

Title source: llm

Description

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.
