Affected Packages

------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/mit-krb5 < 1.11.4 >= 1.11.4

Impact

===== A remote attacker could send a specially crafted request, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. Additionally, a remote attacker could impersonate a kadmind server and send a specially crafted packet to the password change port, which can result in a ping-pong condition and a Denial of Service condition.

Workaround

There is no known workaround at this time.
