The remote Qpopper server, according to its banner, is running version 4.0.3 or version 4.0.4. These versions are vulnerable to a buffer overflow if they are configured to allow the processing of a user’s ~/.qpopper-options file. A local user can cause a buffer overflow by setting the ‘bulldir’ variable to something longer than 256 characters.
*** This test could not confirm the existence of the*** problem - it relied on the banner being returned.
