Description:
Tom Palarz and Kris Kubicki have reported a vulnerability in xlreader, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the "book_format_sql()" function. This can be exploited to cause a buffer overflow by tricking a user into viewing a specially crafted Excel document.

Successful exploitation allows execution of arbitrary code, but requires that the "-s" command line parameter is used.

The vulnerability has been reported in version 0.9.0. Other versions may also be affected.

Solution:
Do not view untrusted Excel documents.

Use another product.
