A flaw was found in the way ICU processed certain, invalid, encoded data. If an application used ICU to decode malformed, multibyte, character data, it may have been possible to bypass certain content protection mechanisms, or display information in a manner misleading to the user. (CVE-2008-1036)

It was discovered that icu, the internal components for Unicode, did not properly sanitise invalid encoded data, which could lead to cross-site scripting attacks.

The remote Oracle Linux 5 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2009-0296 advisory.

    [3.6-5.11.2]
    - Resolves: rhbz#467949 CVE-2008-1036

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is running a version of Mac OS X 10.5.x that is prior to 10.5.3. 

Mac OS X 10.5.3 contains security fixes for a number of programs.

Updated icu packages that fix a security issue are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The International Components for Unicode (ICU) library provides robust and full-featured Unicode services.

A flaw was found in the way ICU processed certain, invalid, encoded data. If an application used ICU to decode malformed, multibyte, character data, it may have been possible to bypass certain content protection mechanisms, or display information in a manner misleading to the user. (CVE-2008-1036)

All users of icu should upgrade to these updated packages, which contain backported patches to resolve these issues.

It was discovered that libicu did not correctly handle certain invalid encoded data. If a user or automated system were tricked into processing specially crafted data with applications linked against libicu, certain content filters could be bypassed.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is running a version of Mac OS X 10.4 that does not have the security update 2008-003 applied. 

This update contains security fixes for a number of programs.

The remote host is running a version of Mac OS X 10.5 that is older than version 10.5.3.  Mac OS X 10.5.3 contains security fixes for a number of programs.
