CVE-2009-1955 medium priority: Debian including 1 source packages (apr-util), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
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.
