| Business Impact: |
Apple QuickTime could allow a remote attacker to execute arbitrary code on the system, caused by a vulnerability related to Java handling. If Java and Quicktime are browser enabled, a remote attacker could exploit this vulnerability by creating a specially-crafted QuickTime file to execute arbitrary code on the system or cause the browser to crash, if the attacker could persuade the victim to view the malicious file or visit a malicious Web site. |

| Technical Description: |
Apple QuickTime for Java extends media handling capability to Java application developers. Vulnerabilities exist in some of the methods available to developers which use JNI to call into native code. These methods allow for traditional memory corruption that is not typically possible through Java.
The most likely attack vector would come in the form of a malicious web site hosting a specially crafted QuickTime for Java applet. We have seen this type of vulnerability leveraged in the past as a malware dropper. |
| Remediation: |
Disabling Java in the browser will prevent the exploitation of this vulnerability.
On Windows systems, renaming QTJavaNative.dll and QTJava.dll in the C:\Program Files\QuickTime\QTSystem\ directory does prevent the attacks from working, but otherwise appears to leave QuickTime unaffected.
Users should be careful not to allow the instatiation of Java applets from untrusted sources.
See References for Apple's patch. |
