FreeBSD UFS/EXT2FS File System Arbitrary Data Access Race
Local Access Required Race Condition
Loss of Confidentiality
Exploit Unknown

- 漏洞描述

FreeBSD contains a flaw that may allow a malicious user to access restricted data which they may not ordinarly have access to. This issue affects the UFS and Ext2FS filesystems. Under certain conditions the filesystem fails to zero deleted blocks before making them available for reuse. It is possible that the flaw may allow disclosure of sensitive data resulting in a loss of confidentiality.
