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.
