    Multiple integer overflows in the Apache Portable Runtime and its Utility

    <p>
    The Apache Portable Runtime (aka APR) provides a set of APIs for
    creating platform-independent applications. The Apache Portable Runtime
    Utility Library (aka APR-Util) provides an interface to functionality
    such as XML parsing, string matching and databases connections.
    </p>

  <description>
    <p>
    Matt Lewis reported multiple Integer overflows in the apr_rmm_malloc(),
    apr_rmm_calloc(), and apr_rmm_realloc() functions in misc/apr_rmm.c of
    APR-Util and in memory/unix/apr_pools.c of APR, both occurring when
    aligning memory blocks.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to connect to a malicious server
    with software that uses the APR or act as a malicious client to a
    server that uses the APR (such as Subversion or Apache servers),
    possibly resulting in the execution of arbitrary code with the
    privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Apache Portable Runtime users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-libs/apr-1.3.8"</code>
    <p>
    All APR Utility Library users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-libs/apr-util-1.3.9"</code>
