Title: Dnsmasq: Denial of Service (GLSA 201512-01)
Date: December 17, 2015
A vulnerability in Dnsmasq can lead to a Denial of Service
Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP
Vulnerable: < 2.72-r2
Unaffected: >= 2.72-r2
Architectures: All supported architectures
An out-of-bounds read vulnerability has been found in the tcp_request
function in Dnsmasq.
A remote attacker could send a specially crafted DNS request, possibly
resulting in a Denial of Service condition.
There is no known workaround at this time.
All Dnsmasq users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/dnsmasq-2.72-r2"
