What is CVE-2017-15088?

A vulnerability in the handling of Distinguished Name (DN) fields within the MIT Kerberos 5 implementation allows remote attackers to exploit this flaw. When untrusted X.509 data is processed, it may lead to arbitrary code execution or cause a denial of service through buffer overflow and application crashes. This issue is particularly relevant in scenarios beyond the standard MIT Kerberos distribution, especially when utilizing KDC certauth plugin code specific to certain environments, such as those developed for Red Hat.
