Mandriva Linux Security Advisory : krb5 (MDVSA-2011:184)

Medium Nessus Plugin ID 61939


The remote Mandriva Linux host is missing one or more security updates.


A vulnerability has been discovered and corrected in krb5 :

The process_tgs_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.9 through 1.9.2 allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS request that triggers an error other than the KRB5_KDB_NOENTRY error (CVE-2011-1530).

The updated packages have been patched to correct this issue.


Update the affected packages.
