Synopsis :

A web browser installed on the remote macOS or Mac OS X host is
affected by multiple vulnerabilities.

Description :

The version of Apple Safari installed on the remote macOS or Mac OS X
host is prior to 10.1.1. It is, therefore, affected by multiple
vulnerabilities :

- An unspecified flaw exists in the history menu
functionality. An unauthenticated, remote attacker can
exploit this to cause a denial of service condition.
(CVE-2017-2495)

- Multiple memory corruption issues exist in the WebKit
component due to improper validation of user-supplied
input. An unauthenticated, remote attacker can exploit
these issues, by convincing a user to visit a specially
crafted website, to execute arbitrary code.
(CVE-2017-2496, CVE-2017-2505, CVE-2017-2506,
CVE-2017-2514, CVE-2017-2515, CVE-2017-2521,
CVE-2017-2525, CVE-2017-2526, CVE-2017-2530,
CVE-2017-2531, CVE-2017-2538, CVE-2017-2539,
CVE-2017-2544, CVE-2017-2547, CVE-2017-6980,
CVE-2017-6984)

- A memory corruption issue exists in the WebKit Web
Inspector component that allows an unauthenticated,
remote attacker to execute arbitrary code.
(CVE-2017-2499)

- An address bar spoofing vulnerability exists due to
improper state management. An unauthenticated, remote
attacker can exploit this to spoof the address in the
address bar. (CVE-2017-2500, CVE-2017-2511)

- Multiple universal cross-site scripting (XSS)
vulnerabilities exist in WebKit due to improper handling
of WebKit Editor commands, container nodes, pageshow
events, frame loading, and cached frames. An
unauthenticated, remote attacker can exploit this, via a
specially crafted web page, to execute arbitrary script
code in a user's browser session. (CVE-2017-2504,
CVE-2017-2508, CVE-2017-2510, CVE-2017-2528,
CVE-2017-2549)

- Multiple unspecified flaws exist in WebKit that allow
an unauthenticated, remote attacker to corrupt memory
and execute arbitrary code by using specially crafted
web content. (CVE-2017-2536)
