Summary
Red Hat Security Advisory: Canna security update
Notes
Topic
The Canna server, used for Japanese character input, has two security
vulnerabilities including an exploitable buffer overflow that allows a local
user to gain 'bin' user privileges. Updated packages for Red Hat Linux
Advanced Server are available.
[Updated 13 Jan 2003]
Added fixed packages for the Itanium (IA64) architecture.
[Updated 06 Feb 2003]
Added fixed packages for Advanced Workstation 2.1
Details
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 can
lead to further exploits. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2002-1158 to this issue.
In addition, it was discovered that request validation was lacking in Canna
server versions 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 Advanced Server ships 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.
