Description:   Multiple vulnerabilities were reported in Adobe Flash Player. A remote user can execute arbitrary code on the target 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 bypass memory address randomization of the Flash heap memory [CVE-2015-3097]. Windows 7 64-bit systems are affected.

A remote user can bypass same-origin-policy and to obtain potentially sensitive information [CVE-2015-3098, CVE-2015-3099, CVE-2015-3102].

A remote user can bypass the cross-site request forgery (CSRF) protections provided in the fix for CVE-2014-5333 [CVE-2015-3096].

A remote user can exploit a permission flaw in the Flash broker for Internet Explorer to gain medium integrity level privileges [CVE-2015-3101].

A remote user can exploit a memory leak to bypass ASLR security protections [CVE-2015-3108].

A remote user can create specially crafted content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A stack overflow may occur [CVE-2015-3100].

An integer overflow may occur [CVE-2015-3104].

A memory corruption error may occur [CVE-2015-3105].

A use-after-free memory error may occur [CVE-2015-3103, CVE-2015-3106, CVE-2015-3107].

Behrang Fouladi Azarnaminy and Axel Souchet of the 360 Vulcan Team, bilou (via the Chromium Vulnerability Reward Program), Chris Evans of Google Project Zero, Haifei Li of McAfee Labs IPS Team, Pujun Li of PKAV team (pkav.net), Malte Batram, Natalie Silvanovich of Google Project Zero, Tomas Polesovsky, and Wen Guanxing from Venustech ADLAB reported these vulnerabilities.

Impact:   A remote user can execute arbitrary code on the target system.

A remote user can obtain potentially sensitive information on the target system.

A remote user can bypass address layout space randomization (ALSR) security protections on the target system.

Solution:   Red Hat has issued a fix for CVE-2015-3096, CVE-2015-3098, CVE-2015-3099, CVE-2015-3100, CVE-2015-3102, CVE-2015-3103, CVE-2015-3104, CVE-2015-3105, CVE-2015-3106 CVE-2015-3107, and CVE-2015-3108.

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

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 APSB15-11
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.
