+ <title>Avahi: "netlink" message vulnerability</title>
+ <synopsis>
+ Avahi fails to verify the origin of netlink messages, which could allow
+ local users to spoof network changes.
+ </synopsis>
+ <product type="ebuild">avahi</product>
+ <announced>2006-11-20</announced>

+ <affected>
+ <package name="net-dns/avahi" auto="yes" arch="*">
+ <unaffected range="ge">0.6.15</unaffected>
+ <vulnerable range="lt">0.6.15</vulnerable>
+ </package>
+ </affected>
+ <background>
+ <p>
+ Avahi is a system that facilitates service discovery on a local
+ network.
+ </p>
+ </background>
+ <description>
+ <p>
+ Avahi does not check that the netlink messages come from the kernel
+ instead of a user-space process.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ A local attacker could exploit this vulnerability by crafting malicious
+ netlink messages and trick Avahi to react to fake network changes. This
+ could lead users to connect to untrusted services without knowing.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Avahi users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-dns/avahi-0.6.15"</code>
