qpopper Options File Buffer Overflow

Critical Nessus Network Monitor Plugin ID 1789


The remote host is vulnerable to a buffer overflow.


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. ***


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