2. Vulnerability Summary

A remotely exploitable vulnerability has been discovered in multiple ACDSee 
Systems products. Specifically, the vulnerability is due to a boundary error 
when processing XBM image files and can lead to a buffer overflow condition. 
This boundary error can allow attackers to inject and execute arbitrary code on 
the target host with the privileges of the logged-on user.

3. Vulnerability Analysis

A remote unauthenticated attacker can exploit the vulnerability by enticing a 
target user to open a maliciously crafted XBM image file. A successful attack

of the logged-on user. An unsuccessful attack can abnormally terminate the 
affected product.
