** Description changed: - Ran ipmi-locate on a system running Focal. ipmi-locate returns the info - I expect to see, and then segfaults (no core dump that I'm aware of). + [Impact] + + * A variable was badly initialized leading to a 0x0 pointer that was + accessed and segfaulting the program. In older versions this was + hidden due to other fails leading to an early exit on such platforms + (those we don't have to touch) + + * The Patch was upstreamed and hereby backported (applies as-is) to + Focal + + [Test Case] + + * There might be more affected systems, but he one we know so far + are dell idrac6/9 so please test on those if possible. + Obviously "regression tests" can be done on any system. + - run ipmi-locate + - without the fix it will segfault + + [Regression Potential] + + * The initialization is done right at the beginning of the function + and not accessed until the bad one we remove. So any user of that + variable would have crashed. Due to that I think we can't regress a + case that wasn't formerly segfaulting - which should be fine. + The one change of behavior is that if people just ran the command (not + checking output) and checked RC for further actions it might now on + some systems actually work and return a difference RC. + + [Other Info] + + * n/a + + --- + + + Ran ipmi-locate on a system running Focal. ipmi-locate returns the info I expect to see, and then segfaults (no core dump that I'm aware of). ubuntu@mayapple:~$ sudo ipmi-locate --version ipmi-locate - 1.6.4 Copyright (C) 2005-2015 FreeIPMI Core Team This program is free software; you may redistribute it under the terms of the GNU General Public License.
