RedHat: RHSA-2010-0829:01 Critical: flash-plugin security update
Summary
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 APSB10-26, 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-2010-3639,
CVE-2010-3640, CVE-2010-3641, CVE-2010-3642, CVE-2010-3643, CVE-2010-3644,
CVE-2010-3645, CVE-2010-3646, CVE-2010-3647, CVE-2010-3648, CVE-2010-3649,
CVE-2010-3650, CVE-2010-3652, CVE-2010-3654)
An input validation flaw was discovered in flash-plugin. Certain server
encodings could lead to a bypass of cross-domain policy file restrictions,
possibly leading to cross-domain information disclosure. (CVE-2010-3636)
During testing, it was discovered that there were regressions with Flash
Player on certain sites, such as fullscreen playback on YouTube. Despite
these regressions, we feel these security flaws are serious enough to
update the package with what Adobe has provided.
All users of Adobe Flash Player should install this updated package, which
upgrades Flash Player to version 10.1.102.64.
