Description

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.
