medium Nessus Plugin ID 84081
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 SUSE host is missing one or more security updates.

Description

The DNS server dnsmasq was updated to fix one security issue and one non-security bug :

CVE-2015-3294: A remote unauthenticated attacker could have caused a denial of service (DoS) or read memory from the heap, potentially disclosing information such as performed DNS queries or encryption keys. (bsc#928867)

bsc#923144: When answer to an upstream query is a CNAME pointing to an A/AAAA record which is present locally (/etc/hosts), allow caching when the upstream and local A/AAAA records have the same value.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
