Debian DLA-385-2 : isc-dhcp regression update

medium Nessus Plugin ID 87931
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security update.

Description

With the previous upload of the isc-dhcp package to Debian Squeeze LTS two issues got introduced into LTS that are resolved by this upload.

(1)

CVE-2015-8605 had only been resolved for the LDAP variant of the DHCP server package built from the isc-dhcp source package. With upload of version 4.1.1-P1-15+squeeze10, now all DHCP server variants (LDAP and non-LDAP alike) include the fix for CVE-2015-8605. Thanks to Ben Hutchings for spotting this inaccuracy.

(2)

The amd64 binary build of the previously uploaded isc-dhcp version (4.1.1-P1-15+squeeze9) was flawed and searched for the dhcpd.conf configuration file at the wrong location [1,2,3]. This flaw in the amd64 build had been caused by a not-100%-pure-squeeze-lts build system on the maintainer's end. The amd64 build of version 4.1.1-P1-15+squeeze10 has been redone in a brand-new build environment and does not show the reported symptom(s) anymore.

I deeply apologize for the experienced inconvenience to all who encountered this issue.
