4 | Subject: [PATCH] vim: patch 8.0.1263: others can read the swap file if a user | ||
5 | is careless | ||
6 | |||
7 | Problem: Others can read the swap file if a user is careless with his | ||
8 | primary group. | ||
9 | Solution: If the group permission allows for reading but the world | ||
10 | permissions doesn't, make sure the group is right. | ||
11 | |||
