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

Red Hat Product Security 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 in the Adobe Security Bulletin APSB15-11 listed in the References section.

Multiple 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 malicious SWF content. (CVE-2015-3100, CVE-2015-3103, CVE-2015-3104, CVE-2015-3105, CVE-2015-3106, CVE-2015-3107)

Multiple security bypass flaws were found in flash-plugin that could lead to the disclosure of sensitive information. (CVE-2015-3096, CVE-2015-3098, CVE-2015-3099, CVE-2015-3102)

A memory information leak flaw was found in flash-plugin that could allow an attacker to potentially bypass ASLR (Address Space Layout Randomization) protection, and make it easier to exploit other flaws.
(CVE-2015-3108)

All users of Adobe Flash Player should install this updated package, which upgrades Flash Player to version 11.2.202.466.

Adobe Flash Player was updated to 11.2.202.466 to fix multiple security issues.

The following vulnerabilities were fixed :

  - CVE-2015-3096: bypass for CVE-2014-5333

  - CVE-2015-3098: vulnerabilities that could be exploited     to bypass the same-origin-policy and lead to information     disclosure

  - CVE-2015-3099: vulnerabilities that could be exploited     to bypass the same-origin-policy and lead to information     disclosure

  - CVE-2015-3100: stack overflow vulnerability that could     lead to code execution

  - CVE-2015-3102: vulnerabilities that could be exploited     to bypass the same-origin-policy and lead to information     disclosure

  - CVE-2015-3103: use-after-free vulnerabilities that could     lead to code execution

  - CVE-2015-3104: integer overflow vulnerability that could     lead to code execution

  - CVE-2015-3105: memory corruption vulnerability that     could lead to code execution

  - CVE-2015-3106: use-after-free vulnerabilities that could     lead to code execution

  - CVE-2015-3107: use-after-free vulnerabilities that could     lead to code execution

  - CVE-2015-3108: memory leak vulnerability that could be     used to bypass ASLR

According to its version, the installation of Adobe AIR on the remote Mac OS X host is equal or prior to 17.0.0.172. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified vulnerability exists that allows an     attacker to bypass the fix for CVE-2014-5333.
    (CVE-2015-3096)

  - Multiple unspecified flaws exist that allow a remote     attacker to bypass the same-origin-policy, resulting in     the disclosure of sensitive information. (CVE-2015-3098,     CVE-2015-3099, CVE-2015-3102)

  - A remote code execution vulnerability exists due to an     unspecified stack overflow flaw. (CVE-2015-3100)

  - A permission flaw exists in the Flash broker for IE     that allows an attacker to perform a privilege     escalation. (CVE-2015-3101)

  - Multiple use-after-free errors exist that allow an     attacker to execute arbitrary code. (CVE-2015-3103,     CVE-2015-3106, CVE-2015-3107)

  - An integer overflow condition exists due to improper     validation of user-supplied input. A remote attacker can     exploit this to execute arbitrary code. (CVE-2015-3104)

  - A memory corruption flaw exists due to improper     validation of user-supplied input. A remote attacker can     exploit this flaw, via specially crafted flash     content, to corrupt memory and execute arbitrary code.
    (CVE-2015-3105)

  - An unspecified memory leak exists that allows an     attacker to bypass the Address Space Layout     Randomization (ASLR) feature. (CVE-2015-3108)

Adobe Flash Player was updated to 11.2.202.466 to fix multiple security issues.
