Date:  May 13 2015
Impact:   Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 17.0.0.169 and prior; other versions affected
Description:   Multiple vulnerabilities were reported in Adobe Flash Player. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can obtain potentially sensitive information on the target system. A remote user can bypass security controls on the target system.

A remote user can create a specially crafted file that, when loaded by the target user, will execute arbitrary code on the target system. The code will run with the privileges of the target user.

A memory corruption error may occur [CVE-2015-3078, CVE-2015-3089, CVE-2015-3090, CVE-2015-3093].

A heap overflow may occur [CVE-2015-3088].

An integer overflow may occur [CVE-2015-3087].

A type confusion error may occur [CVE-2015-3077, CVE-2015-3084, CVE-2015-3086].

A use-after-free memory error may occur [CVE-2015-3080].

A user can bypass a time-of-check time-of-use (TOCTOU) race condition to bypass Protected Mode in Internet Explorer [CVE-2015-3081]

A remote user can bypass validation to write arbitrary data to the target file system [CVE-2015-3082, CVE-2015-3083, CVE-2015-3085].

A remote user can trigger a memory leak to bypass address space layout randomization (ASLR) protections [CVE-2015-3091, CVE-2015-3092].

A remote user can bypass security controls to obtain potentially sensitive information [CVE-2015-3079].

bilou (via the Chromium Vulnerability Reward Program), Chris Evans of Google Project Zero, Jietao Yang and Jihui Lu of KeenTeam (@K33nTeam), Jouko Pynnonen of Klikki Oy, Natalie Silvanovich of Google Project Zero, and Nicolas Joly (via HP's Zero Day Initiative) reported these vulnerabilities.

Impact:   A remote user can create a file that, when loaded by the target user, will execute arbitrary code, obtain potentially sensitive information, or bypass security controls on the target user's system.
Solution:   Red Hat has issued a fix.

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop Supplementary (v. 5) - i386, x86_64
Red Hat Enterprise Linux Desktop Supplementary (v. 6) - i386, x86_64
Red Hat Enterprise Linux Server Supplementary (v. 5) - i386, x86_64

Red Hat Enterprise Linux Workstation Supplementary (v. 6) - i386, x86_64

3. Description:

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 APSB15-09
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-2015-3077, CVE-2015-3078, CVE-2015-3080, CVE-2015-3082,
CVE-2015-3083, CVE-2015-3084, CVE-2015-3085, CVE-2015-3086, CVE-2015-3087,
CVE-2015-3088, CVE-2015-3089, CVE-2015-3090, CVE-2015-3093)

A security bypass flaw was found in flash-plugin that could lead to the
disclosure of sensitive information. (CVE-2015-3079)

Two memory information leak flaws were 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-2015-3091, CVE-2015-3092)

All users of Adobe Flash Player should install this updated package, which
upgrades Flash Player to version 11.2.202.460.
