Adobe Product Security Incident Response Team reports :

Critical vulnerabilities have been identified in Adobe Flash Player 10.2.159.1 and earlier versions (Adobe Flash Player 10.2.154.28 and earlier for Chrome users) for Windows, Macintosh, Linux and Solaris, and Adobe Flash Player 10.2.157.51 and earlier versions for Android.
These vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system.
There are reports of malware attempting to exploit one of the vulnerabilities, CVE-2011-0627, in the wild via a Flash (.swf) file embedded in a Microsoft Word (.doc) or Microsoft Excel (.xls) file delivered as an email attachment targeting the Windows platform.
However, to date, Adobe has not obtained a sample that successfully completes an attack.

Several critical vulnerabilities exist in versions of Flash Player earlier than 10.3.181.14 :

  - An unspecified information disclosure vulnerability     exists. (CVE-2011-0579)

  - An unspecified integer overflow vulnerability exists.
    (CVE-2011-0618, CVE-2011-0628)

  - Unspecified memory corruption vulnerabilities exist.
    (CVE-2011-0619, CVE-2011-0620, CVE-2011-0621,     CVE-2011-0622, CVE-2011-0627)

  - Unspecified boundary-checking errors exist.
    (CVE-2011-0623, CVE-2011-0624, CVE-2011-0625,     CVE-2011-0626)

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.

An updated Adobe Flash Player package that fixes multiple security issues is now available for Red Hat Enterprise Linux 5 and 6 Supplementary.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash Player web browser plug-in.

This update fixes multiple vulnerabilities in Adobe Flash Player.
These vulnerabilities are detailed on the Adobe security page APSB11-12, listed in the References section.

Multiple security flaws were found in the way flash-plugin displayed certain SWF content. An attacker could use these flaws to create a specially crafted SWF file that would cause flash-plugin to crash or, potentially, execute arbitrary code when the victim loaded a page containing the specially crafted SWF content. (CVE-2011-0618, CVE-2011-0619, CVE-2011-0620, CVE-2011-0621, CVE-2011-0622, CVE-2011-0623, CVE-2011-0624, CVE-2011-0625, CVE-2011-0626, CVE-2011-0627)

This update also fixes an information disclosure flaw in flash-plugin.
(CVE-2011-0579)

All users of Adobe Flash Player should install this updated package, which upgrades Flash Player to version 10.3.181.14.

According to its version, the instance of Flash Player installed on the remote Mac OS X host is earlier than 10.3.181.14.  Such versions are reportedly affected by the following vulnerabilities :

  - An unspecified information disclosure vulnerability     exists. (CVE-2011-0579)

  - An unspecified integer overflow vulnerability exists.
    (CVE-2011-0618)

  - Unspecified memory corruption vulnerabilities exist.
    (CVE-2011-0619, CVE-2011-0620, CVE-2011-0621,     CVE-2011-0622, CVE-2011-0627)

  - Unspecified boundary-checking errors exist.
    (CVE-2011-0623, CVE-2011-0624, CVE-2011-0625,     CVE-2011-0626)

The remote host is affected by the vulnerability described in GLSA-201110-11 (Adobe Flash Player: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Adobe Flash Player.
      Please review the CVE identifiers and Adobe Security Advisories and       Bulletins referenced below for details.
  Impact :

    By enticing a user to open a specially crafted SWF file a remote       attacker could cause a Denial of Service or the execution of arbitrary       code with the privileges of the user running the application.
  Workaround :

    There is no known workaround at this time.
