Comment 2 Nick Clifton 2019-02-26 12:08:32 UTC
This is not a CVE.  A corrupt input file is causing one of the binutils tools
to attempt to allocate more memory than is available on the host machine.  Under
normal circumstances this allocation will fail, the tool will detect the failure
and correctly report an "out of memory" error.  The CVE was filed against a version
of the tool which had been compiled with address sanitization enabled, which
meant that the over-large memory allocation was caught and flagged as an error
before the tool could handle it.
