A vulnerability was found in elfutils. A maliciously crafted ELF file could cause a very large allocation failure.

Note that the real bug wasn't a crash (unless the application made malloc abort when an allocation failed) but a possibly very large allocation failure. The fix was to limit the maximum amount of memory the library would allocated to the file size that was being read.
