** Bug watch added: Debian Bug tracker #837732 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=837732 ** Also affects: ifupdown (Ubuntu Xenial) Importance: Undecided Status: New ** Description changed: + [Impact] + ifup and ifupdown segfault if multiple interfaces are listed in no-scripts + This is a trivially reproducible crash in ifup/ifdown, with a patch attached. + [Test Case] Steps to reproduce: 1) echo no-scripts foo bar >> /etc/network/interfaces 2) ifup baz Expected results: Unknown interface baz Actual results: Segmentation fault (core dumped) It's irrelevant whether the second interface is on the same no-scripts line or separate one. This will crash just the same: echo no-scripts foo >> /etc/network/interfaces echo no-scripts bar >> /etc/network/interfaces + + [Regression potential] + Seems slight. The patch fixes a clear bug in code that is only used to process the no-scripts (and apparently no-auto-down) stanzas. ** Changed in: ifupdown (Ubuntu) Status: New => Fix Committed ** Changed in: ifupdown (Ubuntu Xenial) Status: New => In Progress -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ifupdown in Ubuntu. https://bugs.launchpad.net/bugs/1618726 Title: ifup & ifdown crash if multiple interfaces are listed in no-scripts Status in ifupdown package in Ubuntu: Fix Committed Status in ifupdown source package in Xenial: In Progress Bug description: [Impact] ifup and ifupdown segfault if multiple interfaces are listed in no-scripts This is a trivially reproducible crash in ifup/ifdown, with a patch attached.
