Are any versions of Qpopper vulnerable to remote exploit?
Qpopper 2.41 and prior versions (and some early beta versions of Qpopper 3.0) are vulnerable to buffer overflow. Remote users can obtain root access on systems running these versions. Qpopper 2.53 and earlier have a non-root exploit. Releases of Qpopper 4.0.5 and later are immune from all known buffer overrun and other security issues. Please upgrade your server if you are running any Qpopper older than the current version Also, 4.0 and later has new code which makes future buffer overruns far less likely, and releases are run against a utility which tests all parameters of all commands for buffer overruns.
