Synopsis :

The remote host contains a web browser that is affected by several
vulnerabilities.

Description :

The version of Safari installed on the remote Mac OS X host is
earlier than 4.0.5. As such, it is potentially affected by several
issues :

- An implementation issue in the handling of cookies set
by RSS and Atom feeds could result in a cookie being
set when visiting or updating a feed even if Safari is
configured to block cookies via the 'Accept Cookies'
preference. (CVE-2010-0044)

- A memory corruption issue in WebKit's handling of CSS
format() arguments could lead to a crash or arbitrary
code execution. (CVE-2010-0046)

- A use-after-free issue in the handling of HTML object
element fallback content could lead to a crash or
arbitrary code execution. (CVE-2010-0047)

- A use-after-free issue in WebKit's parsing of XML
documents could lead to a crash or arbitrary code
execution. (CVE-2010-0048)

- A use-after-free issue in the handling of HTML elements
containing right-to-left displayed text could lead to a
crash or arbitrary code execution. (CVE-2010-0049)

- A use-after-free issue in WebKit's handling of
incorrectly nested HTML tags could lead to a crash or
arbitrary code execution. (CVE-2010-0050)

- An implementation issue in WebKit's handling of cross-
origin stylesheet requests when visiting a malicious
website could result in disclosure of the content of
protected resources on another website. (CVE-2010-0051)

- A use-after-free issue in WebKit's handling of
callbacks for HTML elements could lead to a crash or
arbitrary code execution. (CVE-2010-0052)

- A use-after-free issue in the rendering of content with
a CSS display property set to 'run-in' could lead to a
crash or arbitrary code execution. (CVE-2010-0053)

- A use-after-free issue in WebKit's handling of HTML
image elements could lead to a crash or arbitrary code
execution. (CVE-2010-0054)
