CVE-2012-3955

Publication date 13 September 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

ISC DHCP 4.1.x before 4.1-ESV-R7 and 4.2.x before 4.2.4-P2 allows remote attackers to cause a denial of service (daemon crash) in opportunistic circumstances by establishing an IPv6 lease in an environment where the lease expiration time is later reduced.
