This update fixes multiple vulnerabilities in Adobe Flash Player. These vulnerabilities are detailed on the Adobe security page APSB10-26
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.
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.
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.
