WebKit, as used in Apple Safari before 5.0.4 and iOS before 4.3, does not properly handle unspecified "cached resources," which allows remote attackers to cause a denial of service (resource unavailability) via a crafted web site that conducts a cache-poisoning attack.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - WebKit, as used in Apple Safari before 5.0.4 and iOS before 4.3, does not properly handle unspecified     cached resources, which allows remote attackers to cause a denial of service (resource unavailability)     via a crafted web site that conducts a cache-poisoning attack. (CVE-2011-0163)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host has Safari installed.

Versions of Safari earlier than 5.0.4 are potentially affected by several issues in the following component :

  - ImageIO

  - libxml

  - WebKit

The remote mobile host is a using a version of Apple iOS earlier than 4.3. Such versions are potentially affected by multiple vulnerabilities. Apple iOS 4.3 contains security fixes for the following components :

  - CoreGraphics

  - ImageIO

  - libxml

  - Networking

  - Safari

  - WebKit

  - Wi-Fi

The remote host has Safari installed.  Versions of Safari earlier than 5.0.4 are potentially affected by several issues in the following component :

  - ImageIO

  - libxml

  - WebKit

The version of Safari installed on the remote Windows host is earlier than 5.0.4.  It therefore is potentially affected by several issues in the following components :

  - ImageIO

  - libxml

  - WebKit

The version of Apple Safari installed on the remote Mac OS X host is earlier than 5.0.4. As such, it is potentially affected by several issues in the following components :

  - libxml

  - WebKit
