Scott Gayou <sgayou at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sgayou at redhat dot com --- Comment #10 from Scott Gayou <sgayou at redhat dot com> --- This reproducer seems to require adjusting the maximum stack size. i.e.: $ ulimit -s 8192 && c++filt < poc -t does NOT crash whereas: $ ulimit -s 2048 && c++filt < poc -t Segmentation fault (core dumped) This looks to be another potentially duplicated CVE. See the following: CVE-2018-18484: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87636 CVE-2018-18701: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87675 CVE-2018-18700: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87681 All appear to be the same root cause.
