Vendor Patch

CVE Reference(s):

Description


Some vulnerabilities have been reported in Apple Safari, which can be exploited by malicious people to compromise a user's system.

1) A boundary error in libxml can be exploited to cause a heap-based buffer overflow and potentially execute arbitrary code.

For more information see vulnerability #2 in:
SA31558

2) Multiple input validation errors in the processing of "feed:" URLs can be exploited to execute arbitrary JavaScript code in a privileged context.

Successful exploitation allows execution of arbitrary code.

3) A input validation error in WebKit when parsing SVGList objects (e.g. "SVGTransformList", "SVGStringList", "SVGNumberList", "SVGPathSegList", "SVGPointList", "SVGLengthList") via the SVGPathList data structure can be exploited to corrupt memory and potentially execute arbitrary code via a negative index passed to the "insertItemBefore()" method.

The vulnerabilities are reported in versions prior to 3.2.3.


Solution:
Apply Security Update 2009-002 or update to version 3.2.3.
