|Gentoo Linux Security Advisory
Title: ISC DHCP: Denial of Service (GLSA 201401-05)
Date: January 06, 2014
A memory exhaustion vulnerability in ISC DHCP could lead to Denial
ISC DHCP is a Dynamic Host Configuration Protocol (DHCP) client/server.
Vulnerable: < 4.2.5_p1
Unaffected: >= 4.2.5_p1
Architectures: All supported architectures
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
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"
