rh#1779573 libyang up to version 1 release 4 has a stack-based buffer overflow in function make_canonical() in parser.c, when dealing with "bits" types with a name longer than 511 bytes. An application that uses libyang to validate untrusted YANG files could be vulnerable to this flaw, which could be used by an attacker to cause a denial of service or possibly gain code execution.
