+ <title>dnsmasq: Denial of Service and DNS spoofing</title>
+ <synopsis>
+ Two vulnerabilities in dnsmasq might allow for a Denial of Service or
+ spoofing of DNS replies.
+ </synopsis>
+ <product type="ebuild">dnsmasq</product>
+ <announced>2008-09-04</announced>
+ <revised>2008-09-04: 01</revised>
+ <bug>231282</bug>
+ <bug>232523</bug>
+ <access>remote</access>
+ <affected>
+ <package name="net-dns/dnsmasq" auto="yes" arch="*">
+ <unaffected range="ge">2.45</unaffected>
+ <vulnerable range="lt">2.45</vulnerable>
+ </package>
+ </affected>
+ <background>
+ <p>
+ Dnsmasq is a lightweight and easily-configurable DNS forwarder and DHCP
+ server.
+ </p>
+ </background>
+ <description>
+ <ul>
+ <li>
+ Dan Kaminsky of IOActive reported that dnsmasq does not randomize UDP
+ source ports when forwarding DNS queries to a recursing DNS server
+ (CVE-2008-1447).
+ </li>
+ <li>
+ Carlos Carvalho reported that dnsmasq in the 2.43 version does not
+ properly handle clients sending inform or renewal queries for unknown
+ DHCP leases, leading to a crash (CVE-2008-3350).
+ </li>
+ </ul>
+ </description>
+ <impact type="normal">
+ <p>
+ A remote attacker could send spoofed DNS response traffic to dnsmasq,
+ possibly involving generating queries via multiple vectors, and spoof
+ DNS replies, which could e.g. lead to the redirection of web or mail
+ traffic to malicious sites. Furthermore, an attacker could generate
+ invalid DHCP traffic and cause a Denial of Service.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All dnsmasq users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-dns/dnsmasq-2.45"</code>
+ </resolution>
