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

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>
|

<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 ">=dev-libs/apr-util-1.3.7"</code>
