CVE-1999-1099

Summary

CVE-1999-1099 is a vulnerability affecting the Kerberos 4 authentication protocol. This issue allows remote attackers to obtain sensitive information, including realm names and the last user, by sending a malformed UDP packet. The error string generated by the protocol inadvertently reveals this information, posing a significant security risk. Attackers can exploit this vulnerability to gain unauthorized access to protected systems or steal confidential data. The Kerberos 4 protocol is outdated and no longer supported, but systems that still use it are at risk until they are upgraded or patched.
