  <title>Compress::Zlib: Buffer overflow</title>
  <synopsis>
    Compress::Zlib is vulnerable to a buffer overflow which could potentially
    lead to execution of arbitrary code.

  <affected>
    <package name="perl-core/Compress-Zlib" auto="yes" arch="*">

  <background>
    <p>
    The Compress::Zlib is a Perl module which provides an interface to
    the zlib compression library.
    </p>
  </background>
  <description>
    <p>
    Compress::Zlib 1.34 contains a local vulnerable version of zlib,
    which may lead to a buffer overflow.
    </p>
  </description>
  <impact type="high">
    <p>
    By creating a specially crafted compressed data stream, attackers
    can overwrite data structures for applications that use Compress::Zlib,
    resulting in a Denial of Service and potentially arbitrary code
    execution.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Compress::Zlib users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=perl-core/Compress-Zlib-1.35"</code>
  </resolution>
