Tom Ferris from security-protocols has reported some potential vulnerabilities in Mac OS X, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a user’s system.

The vulnerabilities exists in the way Mac OS X and the Safari browser handles zip and images files. Visiting a web site with a crafted malformed image (bmp, tiff, gif) file can potentially compromise a user’s system.

The vulnerabilities have been reported in version 10.4.6. Other versions may also be affected. Security web site Secunia rated these vulnerabilities as Highly critical and recommends not to visit untrusted web sites, and not to open ZIP archives or images originating from untrusted sources.
