The code which expands the array incorrectly calculates its new size when requesting memory, resulting in a heap buffer overrun.</p> <p>A specially crafted packet can cause dhclient to overrun its buffer of environment entries. This can result in a crash, but it may be possible to leverage this bug to achieve remote code execution.</p> <p><strong>Affected:</strong> FreeBSD</p> <p>As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of string pointers.
