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 :
