Adobe Flash Player: Multiple vulnerabilities

Background

The Adobe Flash Player is a renderer for the SWF file format, which is commonly used to provide interactive websites.

Description

Multiple vulnerabilities have been discovered in Adobe Flash Player:

• An anonymous researcher working with the Zero Day Initiative reported that Adobe Flash Player does not properly process JPEG files (CVE-2009-3794).
• Jim Cheng of EffectiveUI reported an unspecified data injection vulnerability (CVE-2009-3796).
• Bing Liu of Fortinet’s FortiGuard Labs reported multiple unspecified memory corruption vulnerabilities (CVE-2009-3797, CVE-2009-3798).
• Damian Put reported an integer overflow in the Verifier::parseExceptionHandlers() function (CVE-2009-3799).
• Will Dormann of CERT reported multiple unspecified Denial of Service vulnerabilities (CVE-2009-3800).

Impact

A remote attacker could entice a user to open a specially crafted SWF file, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application, or a Denial of Service via unknown vectors.

Workaround

There is no known workaround at this time.

Resolution

All Adobe Flash Player users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-plugins/adobe-flash-10.0.42.34"
