Synopsis:	Moderate: krb5 security update
Issue date:	2010-11-30
CVE Names:	CVE-2010-1323

Multiple checksum validation flaws were discovered in the MIT Kerberos
implementation. A remote attacker could use these flaws to tamper with
certain Kerberos protocol packets and, possibly, bypass authentication
mechanisms in certain configurations using Single-use Authentication
Mechanisms. (CVE-2010-1323)

After installing the updated packages, the krb5kdc daemon will be
restarted automatically.
