Mandriva Linux Security Advisory : krb5 (MDVSA-2013:158)

Medium Nessus Plugin ID 66285


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


A vulnerability has been discovered and corrected in krb5 :

The prep_reprocess_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.5 does not properly perform service-principal realm referral, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS-REQ request (CVE-2013-1416).

The updated packages have been patched to correct this issue.


Update the affected packages.
