Fedora Legacy Update Advisory

Synopsis: Updated sysklogd resolves memory buffer bug
Advisory ID: FLSA:1553

Keywords: Bugfix

1. Topic:

Updated sysklogd packages that fixes a memory buffer bug are now available.

2. Relevent releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386

3. Problem description:

The sysklogd package contains two system utilities (syslogd and klogd) that provide support for system logging. Syslogd and klogd run as daemons and log system messages to different places, like sendmail logs, security logs, and error logs.

During a code review it was discovered that syslogd does not allocate enough memory to store all its pointers in the crunch list. Without it, the array is not big enough and unexpected results (or core dump) may follow.

All users are advised to upgrade to these updated packages, which contain a backported fix and are not vulnerable to this issue.

Fedora Legacy would like to thank Rok Papez for reporting this issue.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.

Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www fedoralegacy.org/docs for directions on how to configure yum
and apt-get.
