Advisory: RHSA-2003:047-15
Type: Security Advisory
Severity: N/A
Issued on: 2003-06-03
Last updated on: 2003-06-03
Affected Products: Red Hat Linux 7.1

CVEs (cve.mitre.org): CVE-2002-1155

Details

A buffer overflow in kon2 allows local users to obtain root privileges.

KON is a Kanji emulator for the console. There is a buffer overflow
vulnerability in the command line parsing code portion of the kon program
up to and including version 0.3.9b. This vulnerability, if appropriately
exploited, can lead to local users being able to gain elevated (root)
privileges.

All users of kon2 should update to these erratum packages, which contain a
patch to fix this vulnerability.

Red Hat would like to thank Janusz Niewiadomski for notifying us of this issue.


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 Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
