NetBSD mail Record File Permission Weakness Information Disclosure
Local Access Required Information Disclosure
Loss of Confidentiality
Exploit Public

- 漏洞描述

NetBSD contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when the "set record" setting is present in a users .mailrc and the default umask is set, which will create a record file with insecure permissions. This will disclose the record file of a user's email resulting in a loss of confidentiality.
