  <title>Kiax: Arbitrary code execution</title>
  <synopsis>
    A security vulnerability in the iaxclient library could lead to the
    execution of arbitrary code by a remote attacker.
  </synopsis>

  <affected>
    <package name="net-misc/kiax" auto="yes" arch="*">
      <unaffected range="ge">0.8.5_p1</unaffected>
      <vulnerable range="lt">0.8.5_p1</vulnerable>
    </package>
  </affected>
  <background>
    <p>
    Kiax is a graphical softphone supporting the IAX protocol (Inter
    Asterisk eXchange), which allows PC users to make VoIP calls to
    Asterisk servers.
    </p>
  </background>
  <description>
    <p>
    The iax_net_read function in the iaxclient library fails to properly
    handle IAX2 packets with truncated full frames or mini-frames. These
    frames are detected in a length check but processed anyway, leading to
    buffer overflows.
    </p>
  </description>
  <impact type="normal">
    <p>
    By sending a specially crafted IAX2 packet, an attacker could execute
    arbitrary code with the permissions of the user running Kiax.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Kiax users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-misc/kiax-0.8.5_p1&quot;</code>
  </resolution>
