#18086 new defect

vboxa uthentication segfaults SQW01

Reported by: oddsocks Owned by:

Description

When using the VirtualBox web service to login, the authentication backend segfaults after a successful login. In order to be able to login again, I have to restart the web service. This has been happening for several releases of VirtualBox now.

I see the following in dmesg

[147969.086688] SQW01[17397]: segfault at 7f9e6da76700 ip 00007f9e6da76700 sp 00007f9e6e3366f8 error 14 in libcap-ng.so.0.0.0[7f9e6d8ee000+200000] [147969.086705] Code: Bad RIP value.

I'm currently running VirtualBox-5.2-5.2.20_125813_fedora26-1.x86_64 on Fedora 28.

The server has been upgraded to Fedora 29 (from F28) and the issue still occurs. For example

Would a coredump or something like that be useful?

Seems to have resolved itself under F29 + VB 5.2.22
