NULL pointer dereference in the _fields_add function in fields.c in libbibcore.a in bibutils through 6.2 allows remote attackers to cause a denial of service (application crash), as demonstrated by end2xml.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
