An issue was discovered in certain Apple products. iOS before 11.2 is affected. Safari before 11.0.2 is affected. iCloud before 7.2 on Windows is affected. iTunes before 12.7.2 on Windows is affected. tvOS before 11.2 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

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.
