CONECTIVA LINUX SECURITY ANNOUNCEMENT


PACKAGE   : sysklogd
SUMMARY   : Format bug in klogd and other issues
DATE      : 2000-09-18 19:31:00
RELEVANT
RELEASES  : 4.0, 4.0es, 4.1, 4.2, 5.0, prg gráficos, ecommerce, 5.1

DESCRIPTION
Vulnerabilities have been found in the sysklogd package that, if exploited, would allow local users to obtain root access. It is also possible that a remote exploit could be used under certain circumstances. The main issue are two calls to Syslog in klogd.c which are vulnerable to a format string attack.

SOLUTION
All users must upgrade immediately. Please note that the syslog service must be restarted in order for the new version to be used. As root, issue the following command:

/etc/rc.d/init.d/syslog restart

We would like to thank Jouko Pynnönen for warning the linux distributions, Solar Designer for providing the main security fixes and Daniel Jacobowitz and the sysklogd maintainers and contributors for providing other fixes.

All packages are signed with Conectiva's GPG key. The key can be obtained at http://www.conectiva.com.br/contato
