Cross references:=20=20 Obsoletes:=20=20=20=20=20=20=20=20=20 CVE Names: CAN-2002-1158 CAN-2002-1159 --------------------------------------------------------------------- 1. Topic: 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. 2. Relevant releases/architectures: Red Hat Linux 7.1 - alpha, i386, ia64 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 3. Problem description: Canna is a kana-kanji conversion server which is necessary for Japanese language character input.=20 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. 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 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. 5.
