Name of the Vulnerable Software and Affected Versions dhcpcd versions 3.x

Description The issue is related to the decode search function in dhcp.c, which allows remote DHCP servers to cause a denial of service through an out-of-bounds read via a crafted response.

Recommendations For dhcpcd versions 3.x, consider disabling the decode search function as a temporary workaround until a patch is available. Restrict access to the dhcp.c module to minimize the risk of exploitation. Avoid using the affected function in the DHCP response handling until the issue is resolved.
