A memory exhaustion vulnerability in ISC DHCP could lead to Denial of Service.
|Package||net-misc/dhcp on all architectures|
|Affected versions||< 4.2.5_p1|
|Unaffected versions||>= 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"
