[ESA-20021029-028] syslog-ng: buffer overflow in macro handling code (UPDATED)

by Nikola Strahija on October 29th, 2002 While reviewing the syslog-ng fixes made in ESA-20021016-025, Sebastian Krahmer discovered that the fixes were not sufficient. This update does a better job of fixing the buffer overflow and supersedes ESA-20021016-025.


SOLUTION
- --------
Users of the EnGarde Professional edition can use the Guardian Digital
Secure Network to update their systems automatically.

EnGarde Community users should upgrade to the most recent version
as outlined in this advisory. Updates may be obtained from:

ftp://ftp.engardelinux.org/pub/engarde/stable/updates/
http://ftp.engardelinux.org/pub/engarde/stable/updates/

Before upgrading the package, the machine must either:

a) be booted into a "standard" kernel; or
b) have LIDS disabled.

To disable LIDS, execute the command:

# /sbin/lidsadm -S -- -LIDS_GLOBAL

To install the updated package, execute the command:

# rpm -Uvh files

You must now update the LIDS configuration by executing the command:

# /usr/sbin/config_lids.pl

To re-enable LIDS (if it was disabled), execute the command:

# /sbin/lidsadm -S -- +LIDS_GLOBAL

To verify the signatures of the updated packages, execute the command:

# rpm -Kv files
