Summary

The DHCP server implementations by OpenBSD, specifically versions 4.0 through 4.2, are susceptible to a stack-based buffer overflow within the cons_options function. Attackers can take advantage of this vulnerability by sending a specially crafted DHCP request that specifies a maximum message size smaller than the minimum IP MTU. This could allow for arbitrary code execution or result in a denial of service, causing the DHCP daemon to crash. This vulnerability underscores the importance of maintaining updated software and the need for robust security measures within network services.
