Mandriva Linux Security Advisory 2010-202 - The merge_authdata function in kdc_authdata.c in the Key Distribution Center 1.8.x before 1.8.4 does not properly manage an index into an authorization-data list, which allows remote attackers to cause a denial of service , or possibly obtain sensitive information, spoof authorization, or execute arbitrary code, via a TGS request, as demonstrated by a request from a Windows Active Directory client. The updated packages have been patched to correct this issue.
