<p>
The Apache Portable Runtime Utility Library (aka apr-util) provides an
interface to functionality such as XML parsing, string matching and
databases connections.

<description>
<p>
Multiple vulnerabilities have been discovered in the APR Utility
Library:
</p>
<ul>
<li>Matthew Palmer reported a heap-based buffer
underflow while compiling search patterns in the
apr_strmatch_precompile() function in strmatch/apr_strmatch.c
(CVE-2009-0023).</li>
<li>kcope reported that the expat XML parser in
xml/apr_xml.c does not limit the amount of XML entities expanded
recursively (CVE-2009-1955).</li>
<li>C. Michael Pilato reported an
off-by-one error in the apr_brigade_vprintf() function in
buckets/apr_brigade.c (CVE-2009-1956).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could exploit these vulnerabilities to cause a Denial
of Service (crash or memory exhaustion) via an Apache HTTP server
running mod_dav or mod_dav_svn, or using several configuration files.
Additionally, a remote attacker could disclose sensitive information or
cause a Denial of Service by sending a specially crafted input. NOTE:
Only big-endian architectures such as PPC and HPPA are affected by the
latter flaw.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Apache Portable Runtime Utility Library users should upgrade to the
latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/apr-util-1.3.7&quot;</code>
</resolution>
