  <title>UnAce: Buffer overflow and directory traversal vulnerabilities</title>
  <synopsis>UnAce is vulnerable to several buffer overflow and directory
    traversal attacks.

  <affected>
    <package name="app-arch/unace" auto="yes" arch="*">
      <unaffected range="ge">2.5-r3</unaffected>

  <background>
    <p>UnAce is an utility to extract, view and test the contents of an ACE
      archive.
    </p>
  </background>
  <description>
    <p>Ulf Harnhammar discovered that UnAce suffers from buffer overflows when
      testing, unpacking or listing specially crafted ACE archives
      (CAN-2005-0160). He also found out that UnAce is vulnerable to directory
      traversal attacks, if an archive contains “./..” sequences or
      absolute filenames (CAN-2005-0161).
    </p>
  </description>
  <impact type="normal">
    <p>An attacker could exploit the buffer overflows to execute malicious code
      or the directory traversals to overwrite arbitrary files.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All UnAce users should upgrade to the latest available version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-arch/unace-2.5-r3"
    </code>
