[原文]rpc.mountd in SGI IRIX 6.5.25, 6.5.26, and 6.5.27 does not correctly allow access to anonymous clients that connect from a system whose hostname can not be determined. NOTE: while this issue occurs in a security mechanism, there is no apparent attacker role and probably does not satisfy the CVE definition of a vulnerability.

IRIX rpc.mountd Anonymous Access Deny Issue
Remote / Network Access Denial of Service
Loss of Availability
Exploit Unknown

- 漏洞描述

IRIX rpc.mountd contains a flaw that may allow a denial of service. The issue is triggered when rpc.mountd incorrectly denies access to anonymous clients whose hostname is not listed in DNS, NIS or /etc/hosts. If an attacker were able to manipulate one of these naming services it could result in loss of availability to the service for some users.
