Medium Nessus Plugin ID 83793


The remote FreeBSD host is missing one or more security-related updates.


Nick Sampanis reported a potential memory exposure and denial of service vulnerability against dnsmasq 2.72. The CVE entry summarizes this as :

The tcp_request function in Dnsmasq before 2.73rc4 does not properly handle the return value of the setup_reply function, which allows remote attackers to read process memory and cause a denial of service (out-of-bounds read and crash) via a malformed DNS request.'


Update the affected packages.
