Alpine: dhcp: security update to 4.4.3_p1-r0

medium Tenable Self-Hosted Container Security Plugin ID 425652

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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)

 - In ISC DHCP 1.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1 a system with access to a DHCP server,
 sending DHCP packets crafted to include fqdn labels longer than 63 bytes, could eventually cause the
 server to run out of memory. (CVE-2022-2929)
