Description Andrej Nemec 2017-04-10 14:46:21 UTC
elflink.c in the Binary File Descriptor (BFD) library (aka libbfd) has a "member access within null pointer" undefined behavior issue, which might allow attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an "int main() {return 0;}" program.
