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.
