The remote Scientific Linux host is missing one or more security
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.

Update the affected httpd, httpd-devel and / or mod_ssl packages.
