Description:
Michael Lehn has discovered a vulnerability in Mac OS X, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an error in the processing of file association meta data in ZIP archives (stored in the "__MACOSX" folder) and mail messages (defined via the AppleDouble MIME format). This can be exploited to trick users into executing a malicious shell script renamed to a safe file extension stored in a ZIP archive or in a mail attachment.
This can also be exploited automatically via the Safari browser when visiting a malicious web site.
Secunia has constructed a test, which can be used to check if your system is affected by this issue:
http://secunia.com/mac_os_x_command_execution_vulnerability_test/
The vulnerability has been confirmed on a fully patched system with Safari 2.0.3 (417.8), Mail 2.0.5 (746/746.2), and Mac OS X 10.4.5.
