Topic: New im packages are available that fix the insecure handling of temporary files. 2. Relevant releases/architectures: Red Hat Linux 7.0 - noarch Red Hat Linux 7.1 - noarch Red Hat Linux 7.2 - noarch Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 3. Problem description: Internet Message (IM) is a series of user interface commands and backend Perl5 libraries that integrate email and the NetNews user interface. They are designed to be used from both the Mew mail reader for Emacs and the command line. A vulnerability has been discovered by Tatsuya Kinoshita in the way two IM utilities create temporary files. By anticipating the names used to create files and directories stored in /tmp, it may be possible for a local attacker to corrupt or modify data as another user.=20 Red Hat Linux 7, 7.1, and 7.2 included IM packages that are vulnerable to this issue. This erratum includes IM version 143 which is not vulnerable to this issue. Red Hat Linux 7.3, and 8.0 included Mew (Messaging in the Emacs World)=20 packages which included vulnerable versions of IM. This erratum provide updated Mew packages including IM version 143 which is not vulnerable to 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.
