  <title>zip: Path name buffer overflow</title>
  <synopsis>
    zip contains a buffer overflow when creating a ZIP archive of files with
    very long path names. This could lead to the execution of arbitrary code.

  <affected>
    <package name="app-arch/zip" auto="yes" arch="*">

    <p>
    zip is a compression and file packaging utility.
    </p>

  <description>
    <p>
    zip does not check the resulting path length when doing recursive
    folder compression.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could exploit this by enticing another user or web
    application to create an archive including a specially-crafted path
    name, potentially resulting in the execution of arbitrary code with the
    permissions of the user running zip.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All zip users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-arch/zip-2.3-r4&quot;</code>
  </resolution>
