CRITICAL:
Not critical

IMPACT:
DoS

DESCRIPTION:
Yannick von Arx has discovered a vulnerability in Safari, which can
be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error in the processing of "td"
HTML tags with overly large values for the "rowspan" attribute. This
can be exploited to consume a large amount of CPU and memory
resources on a vulnerable system by tricking a user into visiting a
malicious web site.

Successful exploitation causes a vulnerable system to become
unresponsive.

The vulnerability has been confirmed in version 2.0.3 (417.9.2) and
has also been reported in version 1.3.1 (312.3.1). Other versions may
also be affected.

SOLUTION:
Do not visit untrusted web sites while working with unsaved sensitive
information.
