FreeBSD : dhcpcd -- remote code execution/denial of service (092156c9-04d7-11e6-b1ce-002590263bf5)

medium Nessus Plugin ID 90553

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

MITRE reports :

The get_option function in dhcp.c in dhcpcd before 6.2.0, as used in dhcpcd 5.x in Android before 5.1 and other products, does not validate the relationship between length fields and the amount of data, which allows remote DHCP servers to execute arbitrary code or cause a denial of service (memory corruption) via a large length value of an option in a DHCPACK message.

Solution

Update the affected package.
