CVE-2009-1955
The expat XML parser in the apr_xml_* interface in xml/apr_xml.c in
Apache APR-util before 1.3.7, as used in the mod_dav and mod_dav_svn
modules in the Apache HTTP Server, allows remote attackers to cause a
denial of service (memory consumption) via a crafted XML document
containing a large number of nested entity references, as demonstrated
by a PROPFIND request, a similar issue to CVE-2003-1564.

CVE-2009-1956
Off-by-one error in the apr_brigade_vprintf function in Apache
APR-util before 1.3.5 on big-endian platforms allows remote attackers
to obtain sensitive information or cause a denial of service
(application crash) via crafted input.

CVE-2009-0023
The apr_strmatch_precompile function in strmatch/apr_strmatch.c in
Apache APR-util before 1.3.5 allows remote attackers to cause a denial
of service (daemon crash) via crafted input involving (1) a .htaccess
file used with the Apache HTTP Server, (2) the SVNMasterURI directive
in the mod_dav_svn module in the Apache HTTP Server, (3) the
mod_apreq2 module for the Apache HTTP Server, or (4) an application
that uses the libapreq2 library, related to an 'underflow flaw.'");
