--------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated enscript packages fix temporary file handling vulnerabilities Advisory ID: RHSA-2002:012-06 Issue date: 2002-01-14 Updated on: 2002-01-17 Product: Red Hat Linux Keywords: enscript temporary files Cross references: Obsoletes: --------------------------------------------------------------------- 1. Topic: Updated enscript packages that fix insecure handling of temporary files are available. 2. Relevant releases/architectures: Red Hat Linux 6.0 - alpha, i386, sparc Red Hat Linux 6.1 - alpha, i386, sparc Red Hat Linux 6.2 - alpha, i386, sparc Red Hat Linux 7.0 - alpha, i386 Red Hat Linux 7.1 - alpha, i386, ia64 Red Hat Linux 7.2 - i386, ia64 3. Problem description: GNU enscript is a program for converting ASCII files to PostScript(TM). When it creates temporary files, it does so with predictable filenames in a manner that would follow symbolic links. This could allow a local user to overwrite files written by the user running enscript, or read the contents of the temporary files. 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. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 57704 - tmpnam and tempnam 6.
