Adobe products: Multiple vulnerabilities

Background

Adobe Flash Player is a closed-source playback software for Flash SWF files. Adobe Reader is a closed-source PDF reader that plays Flash content as well.

Description

Multiple vulnerabilities have been reported in Adobe Flash Player:

• lakehu of Tencent Security Center reported an unspecified memory corruption vulnerability (CVE-2009-1862).
• Mike Wroe reported an unspecified vulnerability, related to “privilege escalation” (CVE-2009-1863).
• An anonymous researcher through iDefense reported an unspecified heap-based buffer overflow (CVE-2009-1864).
• Chen Chen of Venustech reported an unspecified “null pointer vulnerability” (CVE-2009-1865).
• Chen Chen of Venustech reported an unspecified stack-based buffer overflow (CVE-2009-1866).
• Joran Benker reported that Adobe Flash Player facilitates “clickjacking” attacks (CVE-2009-1867).
• Jun Mao of iDefense reported a heap-based buffer overflow, related to URL parsing (CVE-2009-1868).
• Roee Hay of IBM Rational Application Security reported an unspecified integer overflow (CVE-2009-1869).
• Gareth Heyes and Microsoft Vulnerability Research reported that the sandbox in Adobe Flash Player allows for information disclosure, when “SWFs are saved to the hard drive” (CVE-2009-1870).

Impact

A remote attacker could entice a user to open a specially crafted PDF file or web site containing Adobe Flash (SWF) contents, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service (application crash). Furthermore, a remote attacker could trick a user into clicking a button on a dialog by supplying a specially crafted SWF file and disclose sensitive information by exploiting a sandbox issue.

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-10.0.32.18"
