  <title>libxml2: Remotely exploitable buffer overflow</title>
  <synopsis>
    libxml2 contains multiple buffer overflows which could lead to the
    execution of arbitrary code.

  <affected>
    <package name="dev-libs/libxml2" auto="yes" arch="*">
      <unaffected range="ge">2.6.15</unaffected>

  <background>
    <p>
    libxml2 is an XML parsing library written in C.
    </p>
  </background>
  <description>
    <p>
    Multiple buffer overflows have been detected in the nanoftp and nanohttp
    modules. These modules are responsible for parsing URLs with ftp
    information, and resolving names via DNS.
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker could exploit an application that uses libxml2 by forcing it to
    parse a specially-crafted XML file, potentially causing remote execution of
    arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All libxml2 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-libs/libxml2-2.6.15"</code>
  </resolution>
