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

- An information disclosure vulnerability exists in the
WebKit component due to improper handling of SVG filters.
An unauthenticated, remote attacker can exploit this,
via a timing side-channel attack, to disclose sensitive
cross-domain information. (CVE-2017-7006)

- An unspecified flaw exists that allows an
unauthenticated, remote attacker to spoof the address
bar via a specially crafted website. (CVE-2017-7011)

- Multiple memory corruption issues exists in the 'WebKit
Web Inspector' component due to improper validation of
input. An unauthenticated, remote attacker can exploit
these issues, via a specially crafted web page, to
execute arbitrary code. (CVE-2017-7012)

- Multiple memory corruption issues exist in the WebKit
component due to improper validation of input. An
unauthenticated, remote attacker can exploit these
issues, via a specially crafted web page, to execute
arbitrary code. (CVE-2017-7018, CVE-2017-7020,
CVE-2017-7030, CVE-2017-7034, CVE-2017-7037,
CVE-2017-7039, CVE-2017-7040, CVE-2017-7041,
CVE-2017-7042, CVE-2017-7043, CVE-2017-7046,
CVE-2017-7048, CVE-2017-7049, CVE-2017-7052,
CVE-2017-7055, CVE-2017-7056, CVE-2017-7061)

- A memory corruption issue exists in the 'WebKit Page
Loading' component due to improper validation of input.
An unauthenticated, remote attacker can exploit this,
via a specially crafted web page, to execute arbitrary
code. (CVE-2017-7019)

- Multiple cross-site scripting (XSS) vulnerabilities
exist in the WebKit component in the DOMParser due to
improper validation of user-supplied input before
returning it to users. An unauthenticated, remote
attacker can exploit these issue, via a specially
crafted URL, to execute arbitrary script code in a
user's browser session. (CVE-2017-7038, CVE-2017-7059)

- A denial of service vulnerability exists in the Safari
Printing component. An unauthenticated, remote attacker
can exploit this, via a specially crafted web page, to
create an infinite number of print dialogs.
(CVE-2017-7060)

- An unspecified memory initialization flaw exists in
WebKit. A local attacker can exploit this, via a
specially crafted application, to disclose restricted
memory. (CVE-2017-7064)
