Tan Chew Keong has discovered a vulnerability in QuarkXPress, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the MSWord text-import extension when handling font names. This can be exploited to cause a stack-based buffer overflow via an overly long font name (more than 256 bytes).

Successful exploitation allows execution of arbitrary code when a user imports text from a malicious MSWord document using e.g. the "Rectangle Text Box" tool.

The vulnerability is confirmed in version 7.2. Other versions may also be affected.

Solution
Import text from trusted Word documents only.
