Synopsis:	Moderate: httpd security update
Issue date:	2009-06-16
CVE Names:	CVE-2009-0023 CVE-2009-1955 CVE-2009-1956

An off-by-one overflow flaw was found in the way apr-util processed a
variable list of arguments. An attacker could provide a
specially-crafted string as input for the formatted output conversion
routine, which could, on big-endian platforms, potentially lead to the
disclosure of sensitive information or a denial of service (application
crash). (CVE-2009-1956)

A denial of service flaw was found in the apr-util Extensible Markup
Language (XML) parser. A remote attacker could create a
specially-crafted XML document that would cause excessive memory
consumption when processed by the XML decoding engine. (CVE-2009-1955)

A heap-based underwrite flaw was found in the way apr-util created
compiled forms of particular search patterns. An attacker could
formulate a specially-crafted search keyword, that would overwrite
arbitrary heap memory locations when processed by the pattern
preparation engine. (CVE-2009-0023)

After installing the updated packages, the httpd daemon must be
restarted for the update to take effect.
