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 10.0.3. It is, therefore, affected by multiple
vulnerabilities :

- A prototype access flaw exists in WebKit when handling
exceptions. An unauthenticated, remote attacker can
exploit this, via specially crafted web content, to
disclose cross-origin data. (CVE-2017-2350)

- Multiple memory corruption issues exist in WebKit due to
improper validation of certain unspecified input. An
unauthenticated, remote attacker can exploit these, via
specially crafted web content, to corrupt memory,
resulting in the execution of arbitrary code.
(CVE-2017-2354, CVE-2017-2356, CVE-2017-2362,
CVE-2017-2366, CVE-2017-2369, CVE-2017-2373)

- An unspecified memory initialization flaw exists in
WebKit that allows an unauthenticated, remote attacker
to execute arbitrary code. (CVE-2017-2355)

- An unspecified state management flaw exists that allows
an unauthenticated, remote attacker to spoof the address
bar. (CVE-2017-2359)

- Multiple flaws exist in WebKit when handling page
loading due to improper validation of certain
unspecified input. An unauthenticated, remote attacker
can exploit these, via specially crafted web content, to
disclose cross-origin data. (CVE-2017-2363,
CVE-2017-2364)

- A flaw exists in WebKit when handling variables due to
improper validation of certain unspecified input. An
unauthenticated, remote attacker can exploit this, via
specially crafted web content, to disclose cross-origin
data. (CVE-2017-2365)
