Mac OS X File Association Meta Data Shell Script Execution

Myantispyware team February 23, 2006     No Comment    

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.
