USN-803-1 -- dhcp3 vulnerabilityID: oval:org.secpod.oval:def:700320 | Date: (C)2011-05-13 (M)2021-09-12 |
Class: PATCH | Family: unix |
It was discovered that the DHCP client as included in dhcp3 did not verify the length of certain option fields when processing a response from an IPv4 dhcp server. If a user running Ubuntu 6.06 LTS or 8.04 LTS connected to a malicious dhcp server, a remote attacker could cause a denial of service or execute arbitrary code as the user invoking the program, typically the "dhcp" user. For users running Ubuntu 8.10 or 9.04, a remote attacker should only be able to cause a denial of service in the DHCP client. In Ubuntu 9.04, attackers would also be isolated by the AppArmor dhclient3 profile.
