| Package | Affected versions | Patched versions |
|---|---|---|
| apr-util | < 1.3.7 | 1.3.7 |
| http server | ≥ 2.2.0, < 2.2.12 | 2.2.12 |
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.
