Security Advisory Updated Canna packages fix vulnerabilities

Advisory: RHSA-2002:246-18
Type: Security Advisory
Severity: N/A
Issued on: 2003-02-07
Last updated on: 2003-08-12
Affected Products: Red Hat Linux 7.1
Red Hat Linux 7.2
Red Hat Linux 7.3
Red Hat Linux 8.0
CVEs (cve.mitre.org): CVE-2002-1158
CVE-2002-1159

Details

The Canna server, used for Japanese character input, has two security
vulnerabilities including an exploitable buffer overrun allowing a local
user to gain 'bin' user privileges. Updated packages for Red Hat Linux are
available.

Canna is a kana-kanji conversion server which is necessary for Japanese
language character input.

A buffer overflow bug in the Canna server up to and including version 3.5b2
allows a local user to gain the privileges of the user 'bin' which could
lead to further exploits. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2002-1158 to this issue.

A lack of validation of requests has been found that affects Canna version
3.6 and earlier. A malicious remote user could exploit this vulnerability
to leak information, or cause a denial of service attack. (CAN-2002-1159)

Red Hat Linux 7.1, 7.2, 7.3, and 8.0 ship with a Canna package vulnerable
to these issues; however, the package is normally only installed when
Japanese language support is selected during installation.

All users of Canna are advised to upgrade to these errata packages which
contain a backported security fix and are not vulnerable to this issue.

Red Hat would like to thank hsj and AIDA Shinra for the responsible
disclosure of these issues.


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.
