Allen Wittenauer updated HADOOP-11415:
--------------------------------------
Labels: security (was: )
> Local file system on Linux may create files and directories initially with
> wider permissions than intended.
> -----------------------------------------------------------------------------------------------------------
>
> Key: HADOOP-11415
> URL: https://issues.apache.org/jira/browse/HADOOP-11415
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Reporter: Chris Nauroth
> Labels: security
>
> As discussed in HADOOP-11321, the local file system implements file and
> directory creation as a two-step process: create followed by chmod to set the
> caller's requested permissions. This causes a brief window in which the new
> file or directory may have wider permissions than what the caller requested.
> HADOOP-11321 fixed this specifically for Windows as a side effect of fixing a
> bug in writing to an SMB share. This issue tracks fixing it specifically for
> Linux.
