3. Description:

The flash-plugin package contains a Firefox-compatible Adobe Flash Player
Web browser plug-in.

Multiple input validation flaws were found in the way Flash Player
displayed certain SWF (Shockwave Flash) content. An attacker could use
these flaws to create a specially-crafted SWF file that could cause
flash-plugin to crash, or, possibly, execute arbitrary code when the victim
loaded a page containing the specially-crafted SWF content. (CVE-2009-0520,
CVE-2009-0519)

All users of Adobe Flash Player should install this updated package, which
upgrades Flash Player to version 9.0.159.0.
