CVE-2010-1321

MIT Kerberos 5 < 1.7.1 and 1.8 < 1.8.2 - Authenticated Denial of Service via Missing AP-REQ Authenticator Checksum

Title source: llm

Description

The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing.
