Description Guenther Deschner 2021-07-22 18:50:09 UTC
rpcclient ncacn_ip_tcp:gdw2k19dc[packet]  -Uadministrator%RedHat1234! -c 'winspool_AsyncOpenPrinter \\\\gdw2k19dc 0x02000000'

The above works with samba 4.14.6 but crashes with obvious NULL pointer deref in 4.15.0rc1
Comment 1 Stefan Metzmacher 2021-11-24 08:58:21 UTC
Can someone please post a backtrace here?
