Affected Packages

------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/mit-krb5 < 1.9.2-r1 >= 1.9.2-r1

Impact

===== A remote attacker may be able to execute arbitrary code with the privileges of the administration daemon or the Key Distribution Center (KDC) daemon, cause a Denial of Service condition, or possibly obtain sensitive information. Furthermore, a remote attacker may be able to spoof Kerberos authorization, modify KDC responses, forge user data messages, forge tokens, forge signatures, impersonate a client, modify user-visible prompt text, or have other unspecified impact.

Workaround

There is no known workaround at this time.
