ISC DHCP: Denial of Service A memory exhaustion vulnerability in ISC DHCP could lead to Denial of Service. dhcp January 06, 2014 January 06, 2014: 1 463848 remote 4.2.5_p1 4.2.5_p1

ISC DHCP is a Dynamic Host Configuration Protocol (DHCP) client/server.

ISC DHCP is vulnerable to a memory exhaustion attack involving regular expressions sent by DHCP clients.

A remote attacker could send a specially crafted request from a malicious or spoofed client, potentially leading to a Denial of Service condition.

There is no known workaround at this time.

All ISC DHCP users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/dhcp-4.2.5_p1"
