[Samba] Interesting explorer crash when getting security properties on the root of a share
It doesn't appear to be affecting anything in our environment, but a vendor recently insisted on "seeing" the security properties on a share. When we right-click on a particular share, go to properties and then click on the security tab, explorer crashes and reloads. I tested on a few Windows 10 and 11 boxes and was able to duplicate it. This is in the event log: Fault bucket 1800533262255858029, type 4 Event Name: APPCRASH Response: Not available Cab Id: 0 Problem signature: P1: explorer.exe P2: 10.0.19041.3271 P3: fb42fb94 P4: StackHash_7047 P5: 10.0.19041.3324 P6: da4a9f63 P7: c0000374 P8: PCH_41_FROM_ntdll+0x000000000009DB64 P9: P10: This doesn't occur on every share and appears to be related to the Unix owner/group. The shares that crash had a at least one file owned by BUILTIN\administrators and the group 'users'. After setting them all back to root:root the issue went away. Setting them back to BUILTIN\administrators and the group 'users' didn't reproduce the crash. Like I said, it's not impacting anything even remotely important in our environments, but it was mildly interesting. :) -A
