Closing this bug as invalid. See:
for further details. The deficiency in the libiberty code itself is present in gdb code. But due to a way how the underlying buffer pre-allocated via libiberty is later used in gdb it is not possible to use this flaw in gdb to reach arbitrary code execution (the buffer is zeroed right after allocation, making the invalid write to be limited to the ability to write zeroes only). Therefore as such the maximum available security implication here is a crash.
Red Hat Security Response Team does not consider user-assisted crash of end-user application, such as gdb, to be a security flaw.
