CVE-2010-1321 Detail

Current 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.

Evaluator Impact

Per: http://web.mit.edu/kerberos/advisories/MITKRB5-SA-2010-005.txt 'AFFECTED SOFTWARE ================= * kadmind and other GSS-API server applications in all known releases of MIT krb5, up to and including krb5-1.8.1 * third-party GSS-API server applications that link link against the GSS-API library in all known releases of MIT krb5, up to and including krb5-1.8.1 * Independent implementations of the krb5 GSS-API mechanism may be vulnerable, as the underlying bug is based on plausible (but invalid) assumptions about the Kerberos protocol.'
