Name of the Vulnerable Software and Affected Versions
dhcp versions 4.1.1 through 4.2.3
dhcp versions prior to 4.2.4-P1
dhcp versions prior to 4.1-ESV-R6
Description
The issue involves multiple vulnerabilities in the dhcp package that can lead to a denial of service due to memory consumption. These vulnerabilities can be exploited remotely by sending many requests, causing disruption to the availability of protected information.
Recommendations
For versions 4.1.1, update to version 4.1-ESV-R6 or later.
For versions 4.2.x prior to 4.2.4-P1, update to version 4.2.4-P1 or later.
As a temporary workaround, consider restricting access to the dhcp service to minimize the risk of exploitation.
