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.

The following vulnerability was fixed :

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

The following bug was fixed :

- 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.
