Adobe Product Security Incident Response Team reports :

An important vulnerability has been identified in Adobe Flash Player 10.3.181.16 and earlier versions for Windows, Macintosh, Linux and Solaris, and Adobe Flash Player 10.3.185.22 and earlier versions for Android. This universal cross-site scripting vulnerability (CVE-2011-2107) could be used to take actions on a user's behalf on any website or webmail provider, if the user visits a malicious website. There are reports that this vulnerability is being exploited in the wild in active targeted attacks designed to trick the user into clicking on a malicious link delivered in an email message.

This update fixes a cross-site scripting vulnerability. CVE-2011-2107:
CVSS v2 Base Score: 5.8 (AV:N/AC:M/Au:N/C:P/I:P/A:N)

An unspecified cross-site scripting vulnerability exists in versions of Flash Player earlier than 10.3.181.22 (10.3.181.23 for ActiveX). 

An attacker may be able to leverage this issue to inject and execute arbitrary HTML and script code in a user's browser.

The version of Adobe Reader installed on the remote Mac OS X host is prior to 10.1, 9.4.5, or 8.3. It is, therefore, affected by the following vulnerabilities :

  - Multiple buffer overflow conditions exist that allow an     attacker to execute arbitrary code. (CVE-2011-2094,     CVE-2011-2095, CVE-2011-2097)

  - A heap overflow condition exists that allows an attacker     to execute arbitrary code. (CVE-2011-2096)

  - Multiple memory corruption issues exist that allow an     attacker to execute arbitrary code. (CVE-2011-2098,     CVE-2011-2099, CVE-2011-2103, CVE-2011-2105,     CVE-2011-2106)

  - Multiple memory corruption issues exist that allow an     attacker to crash the application. (CVE-2011-2104,     CVE-2011-2105)

  - A DLL loading vulnerability exists that allows an     attacker to execute arbitrary code. (CVE-2011-2100)

  - A cross-document script execution vulnerability exists     that allows an attacker to execute arbitrary code.
    (CVE-2011-2101)

  - A unspecified vulnerability exists that allows an     attacker to bypass security restrictions. (CVE-2011-2102)

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

According to its version, the instance of Flash Player installed on the remote Mac OS X host is earlier than 10.3.181.22.  As such, it is reportedly affected by an unspecified cross-site scripting vulnerability.

The remote Redhat Enterprise Linux 5 / 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2011:0850 advisory.

  - flash-plugin: Cross-site scripting vulnerability (APSB11-13) (CVE-2011-2107)

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