Google: net-misc/dhcp: security update to 17162.127.27

medium Tenable Cloud Security Plugin ID 453001

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In ISC DHCP 4.4.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1, when the function
option_code_hash_lookup() is called from add_option(), it increases the option's refcount field. However,
there is not a corresponding call to option_dereference() to decrement the refcount field. The function
add_option() is only used in server responses to lease query packets. Each lease query response calls this
function for several options, so eventually, the reference counters could overflow and cause the server to
abort. (CVE-2022-2928)

Solution

Update the net-misc/dhcp library and its related packages to version 17162.127.27 or later.
