[syslog-ng]Security: syslog-ng 1.4.x and 1.5.x is vulnerable to buffer overflow
Fri, 27 Sep 2002 16:16:24 +0200
I'm writing this mail to announce that syslog-ng 1.4.x and 1.5.x are both
vulnerable to a buffer overflow. Exploiting the bug needs a site specific
exploit to be written, as the way the buffer is overwritten depends on the
local configuration file.
The buffer overflow can be triggered when templated output files or filename
templates are used.
Everybody is urged to upgrade to 1.4.16 or 1.5.21, these are available at
the usual place, http://www.balabit.hu/en/downloads/syslog-ng/downloads/
The bug was found be me, so possibly nobody else knows the details. Of
course diffing the new version with the previous one unveils the problem.
Bugtraq announcement will be sent out soon. Debian package has been
released and accepted (though mirrors need time to get the new one)
ps: sigh, this was my first BoF :(
