Description

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.'

Solution

Update the affected packages.
