CONECTIVA LINUX SECURITY ANNOUNCEMENT
- -----------------------------------------------------------------------
PACKAGE : stunnel
SUMMARY : Remote exploit and other bug fixes
DATE : 2000-12-20 12:18:00
ID : CLA-2000:363
RELEVANT
RELEASES : 4.0, 4.0es, 4.1, 4.2, 5.0, 5.1, 6.0
- ----------------------------------------------------------------------
DESCRIPTION
"stunnel" is a package which offers wrapped SSL connections for
generic TCP services, such as pop3, ldap and others.
Versions prior do 3.9 have a format string vulnerability in a
syslog() call which could be exploited remotely. The package
distributed with Conectiva Linux 5.1 and 6.0 has the daemon running
as the "stunnel" user, and not root, which diminishes the effect of
this vulnerability somewhat.
Also, versions prior to 3.8 created the PID file in an insecure
manner, possibly making it vulnerable to symlink attacks depending on
where the user chose to put the PID file.
Other bugs were also fixed in the 3.10 release, please refer to the
Changelog for a full description.
SOLUTION
All stunnel users should upgrade immediatelly.
