GNU Binutils 'libiberty' CVE-2019-14250 Integer Overflow Vulnerability

GNU Binutils is prone to an integer overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer.

Attackers can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will likely cause a denial-of-service condition.

GNU Binutils version 2.32 is vulnerable.
