The sample exploit requires a valid user account and password, and overflows a string in the pop_msg() function to give the user 'mail' group privileges and a shell on the system. Since the Qvsnprintf function is used elsewhere in qpopper, additional exploits may be possible.

The qpopper package in Debian 2.2 (potato) does not include the vulnerable snprintf implementation. For Debian 3.0 (woody) an updated package is available in version 4.0.4-2.woody.3. Users running an unreleased version of Debian should upgrade to 4.0.4-9 or newer. We recommend you upgrade your qpopper package immediately.");
