- 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.
-
- Solution : Upgrade to the latest version, or disable
- processing of user option files.
