CVE Reference(s):

Description


Some vulnerabilities have been reported in Apple iTunes, which can be exploited by malicious, local users to gain escalated privileges and by malicious people to disclose sensitive information, cause a DoS (Denial of Service), or compromise a user's system.

1) Multiple errors in the ColorSync and ImageIO components when handling images can be exploited to disclose application memory or potentially execute arbitrary code.

For more information see vulnerabilities #1 through #4 and #9 in:
SA38932

2) An error when processing MP4 files can be exploited to trigger the execution of an infinite loop and render the application unusable after its restart via e.g. a specially crafted podcast.

3) During installation iTunes for Windows installs and executes certain files in a directory in the ""%ALLUSERSPROFILE%\Application Data\" path. As standard permissions allow any user to write files to the path, this can be exploited to either create malicious files with specific names before installation or malicious libraries after installation, allowing execution of arbitrary code with SYSTEM privileges.

4) An error in the handling of log files for mobile devices can be exploited to gain privileges of the console user when syncing an iPhone, iPad, or iPod touch.

5) A error in the search path handling can be exploited to load a malicious DLL file when a user is tricked into opening a media file from the same directory.

Successful exploitation of this vulnerability allows execution of arbitrary code.

The vulnerabilities are reported in versions prior to 9.1.


Solution:
Update to version 9.1.
