CVE-2015-3294

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
