Topic: Updated ddskk packages which fix a temporary file security issue are now available. 2. Relevant releases/architectures: Red Hat Linux 7.1 - noarch Red Hat Linux 7.2 - noarch Red Hat Linux 7.3 - noarch Red Hat Linux 8.0 - noarch Red Hat Linux 9 - noarch 3. Problem description: Daredevil SKK is a simple Kana to Kanji conversion program, an input method of Japanese for Emacs and XEmacs. ddskk does not take appropriate security precautions when creating temporary files. This bug could potentially be exploited to overwrite arbitrary files with the privileges of the user running Emacs and skk. The Common Vulnerabilities and Exposures project (cve.mitre.org) has allocated the name CAN-2003-0539 to this issue. All users of ddskk should upgrade to these erratum packages containing a backported security patch that corrects 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 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.
