RHSA-2009:0332 - Critical: flash-plugin security update

Synopsis

Critical: flash-plugin security update

Type/Severity

Security Advisory Critical

Topic

An updated Adobe Flash Player package that fixes several security issues is now available for Red Hat Enterprise Linux 5 Supplementary.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

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)

It was discovered that Adobe Flash Player had an insecure RPATH (runtime library search path) set in the ELF (Executable and Linking Format) header. A local user with write access to the directory pointed to by RPATH could use this flaw to execute arbitrary code with the privileges of the user running Adobe Flash Player. (CVE-2009-0521)

All users of Adobe Flash Player should install this updated package, which upgrades Flash Player to version 10.0.22.87.
