Details

It was discovered that krb5 did not correctly handle certain krb4
requests. An unauthenticated remote attacker could exploit this flaw
by sending a specially crafted traffic, which could expose sensitive
information, cause a crash, or execute arbitrary code. (CVE-2008-0062,
CVE-2008-0063)

A flaw was discovered in the kadmind service’s handling of file
descriptors. An unauthenticated remote attacker could send specially
crafted requests that would cause a crash, resulting in a denial of
service. Only systems with configurations allowing large numbers of
open file descriptors were vulnerable. (CVE-2008-0947)
