Severity: normal

Synopsis

A vulnerability in nfs-utils might allow remote attackers to gain
access to restricted information.


Background

on PTR resolution for GSSAPI authentication, allowing for data to be
submitted to a malicious server without the knowledge of the user.


Impact

Workaround

There is no known workaround at this time.

Resolution
