Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS Summary: DHCP could be made to crash if it received specially crafted network traffic. Software Description: - isc-dhcp: DHCP server and client - dhcp3: DHCP server and client Details: Glen Eustace discovered that the DHCP server incorrectly handled IPv6 expiration times. A remote attacker could use this issue to cause DHCP to crash, resulting in a denial of service. This issue only affected Ubuntu 11.04, Ubuntu 11.10 and Ubuntu 12.04 LTS. (CVE-2012-3955) Dan Rosenberg discovered that the DHCP AppArmor profile could be escaped by using environment variables. This update mitigates the issue by sanitizing certain variables in the DHCP shell scripts. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: Ubuntu 11.10: Ubuntu 11.04: Ubuntu 10.04 LTS: In general, a standard system update will make all the necessary changes.

Title: | DSA-2551-1 isc-dhcp - denial of service | ||
Description: | Glen Eustace discovered that the ISC DHCP server, a server for automatic IP address assignment, is not properly handling changes in the expiration times of a lease. An attacker may use this flaw to crash the service and cause denial of service conditions, by reducing the expiration time of an active IPv6 lease. | ||
