The remote Scientific Linux host is missing one or more security updates.


Security Fix(es) :

- A heap buffer overflow was found in dnsmasq in the code responsible for building DNS replies. An attacker could send crafted DNS packets to dnsmasq which would cause it to crash or, potentially, execute arbitrary code.


Update the affected dnsmasq, dnsmasq-debuginfo and / or dnsmasq-utils packages.
