CVE-2011-0043

Estado: ModificadaAlta (7.2)—

Kerberos in Microsoft Windows XP SP2 and SP3 and Server 2003 SP2 supports weak hashing algorithms, which allows local users to gain privileges by operating a service that sends crafted service tickets, as demonstrated by the CRC32 algorithm, aka "Kerberos Unkeyed Checksum Vulnerability."
