Description

Kees Cook discovered that some shadow utilities did not correctly validate
user input. A local attacker could exploit this flaw to inject newlines into
the /etc/passwd file. If the system was configured to use NIS, this could
lead to existing NIS groups or users gaining or losing access to the system,
resulting in a denial of service or unauthorized access.
