[Bug 1671472] Re: Upgrade warns of leaked file descriptors on vgs, lvs invocation

Fri Mar 10 00:26:48 UTC 2017

Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.
