Synopsis:	Moderate: apr-util 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)

Applications using the Apache Portable Runtime library, such as httpd, 
must be restarted for this update to take effect.
