Details
Setting the sticky bit on world writable directories prevents users from deleting or renaming files in that directory that are not owned by them.
Rationale:
This feature prevents the ability to delete or rename files in world writable directories (such as /tmp ) that are owned by another user.
Solution
Run the following command to set the sticky bit on all world writable directories:
# df –local -P | awk ‘{if (NR!=1) print $6}’ | xargs -I ‘{}’ find ‘{}’ -xdev -type d ( -perm -0002 -a ! -perm -1000 ) 2>/dev/null | xargs -I ‘{}’ chmod a+t ‘{}’
