WebKit, as used in Apple Safari before 6.1.4 and 7.x before 7.0.4, does not properly interpret Unicode encoding, which allows remote attackers to spoof a postMessage origin, and bypass intended restrictions on sending a message to a connected frame or window, via crafted characters in a URL.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - WebKit: Improper handling of data types from event objects (CVE-2010-4205)

  - webkitgtk: heap-based buffer overflow (WSA-2015-0001) (CVE-2014-1303)

  - Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and     Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a     denial of service (application crash) via vectors involving HTML document subtrees. (CVE-2010-1761)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - webkitgtk: heap-based buffer overflow (WSA-2015-0001) (CVE-2014-1303)

  - webkitgtk: Processing web content may lead to arbitrary code execution (CVE-2023-40414)

  - Use-after-free vulnerability in Google Chrome before 28.0.1500.71 allows remote attackers to cause a     denial of service or possibly have unspecified other impact via vectors related to the handling of input.
    (CVE-2013-2871)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote host has Safari installed that is older than 6.1.4 or 7.0.4, and is thus unpatched for the following WebKit vulnerabilities :

 - Multiple memory corruption issues within WebKit, which were addressed through improved memory handling (CVE-2013-2875, CVE-2013-2927, CVE-2014-1323, CVE-2014-1324, CVE-2014-1326, CVE-2014-1327, CVE-2014-1329, CVE-2014-1330, CVE-2014-1331, CVE-2014-1333, CVE-2014-1334, CVE-2014-1335, CVE-2014-1336, CVE-2014-1337, CVE-2014-1338, CVE-2014-1339, CVE-2014-1341, CVE-2014-1342, CVE-2014-1343, CVE-2014-1344, CVE-2014-1731)
 - An issue with the way unicode characters in the URL are handled could result in bypassing the browser's origin check (CVE-2014-1346)

The version of Apple Safari installed on the remote Mac OS X host is a version prior to 6.1.4 or 7.0.4. It is, therefore, potentially affected by the following vulnerabilities :

  - Multiple memory corruption vulnerabilities exist in     WebKit that could lead to unexpected program     termination or arbitrary code execution.
    (CVE-2013-2875, CVE-2013-2927, CVE-2014-1323,     CVE-2014-1324, CVE-2014-1326, CVE-2014-1327,     CVE-2014-1329, CVE-2014-1330, CVE-2014-1331,     CVE-2014-1333, CVE-2014-1334, CVE-2014-1335,     CVE-2014-1336, CVE-2014-1337, CVE-2014-1338,     CVE-2014-1339, CVE-2014-1341, CVE-2014-1342,     CVE-2014-1343, CVE-2014-1344, CVE-2014-1731)

  - An error exists related to unicode character handling     in URLs that could allow an attacker send an incorrect     'postMessage' origin that could allow a security bypass.
