Description

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(s)

  • ubuntu-upgrade-dnsmasq
  • ubuntu-upgrade-dnsmasq-base
  • ubuntu-upgrade-dnsmasq-utils

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
