RHSA-2003-297: stunnel

Vulnerability Assessment Summary
Check for the version of the stunnel packages

Detailed Explanation for this Vulnerability Assessment

Updated stunnel packages are now available. These updates address problems
stemming from improper use of non-reentrant functions in signal handlers.

Stunnel is a wrapper for network connections. It can be used to tunnel an
unencrypted network connection over an encrypted connection (encrypted
using SSL or TLS) or to provide an encrypted means of connecting to
services that do not natively support encryption.

A previous advisory provided updated packages to address re-entrancy
problems in stunnel's signal-handling routines. These updates did not
address other bugs that were found by Steve Grubb, and introduced an
additional bug, which was fixed in stunnel 3.26.

All users should upgrade to these errata packages, which address these
issues by updating stunnel to version 3.26.

NOTE: After upgrading, any instances of stunnel configured to run in daemon
mode should be restarted, and any active network connections that are
currently being serviced by stunnel should be terminated and reestablished.
