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 does not properly free allocated memory. This allows remote DHCP servers to cause a denial of service via a crafted response.

Recommendations For dhcpcd versions 3.x, consider updating to a version where the decode search function properly handles memory allocation to prevent denial of service attacks.
