Scientific Linux Security Update : apr-util on SL4.x, SL5.x i386/x86_64
High Nessus Plugin ID 60597
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionAn 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.
SolutionUpdate the affected apr-util, apr-util-devel and / or apr-util-docs packages.
