Red Hat Errata System 5.3 2008-01-23T07:17:58 Red Hat Enterprise Linux 3 Sysstat is a tool for gathering system statistics. Isag is a utility for graphically displaying these statistics. A bug was found in the Red Hat sysstat package post and trigger scripts, which used insecure temporary file names. A local attacker could overwrite system files using carefully-crafted symbolic links in the /tmp directory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0107 to this issue. While fixing this issue, a flaw was discovered in the isag utility, which also used insecure temporary file names. A local attacker could overwrite files that the user running isag has write access to using carefully-crafted symbolic links in the /tmp directory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0108 to this issue. Other issues addressed in this advisory include: * iostat -x should return all partitions on the system (up to a maximum of 1024) * sar should handle network device names with more than 8 characters properly * mpstat should work correctly with more than 7 CPUs as well as generate correct statistics when accessing individual CPUs. This issue only affected Red Hat Enterprise Linux 2.1 * The sysstat package was not built with the proper dependencies; therefore, it was possible that isag could not be run because the necessary tools were not available. Therefore, isag was split off into its own subpackage with the required dependencies in place. This issue only affects Red Hat Enterprise Linux 2.1. Users of sysstat and isag should upgrade to these updated packages, which contain patches to correct these issues. NOTE: In order to use isag on Red Hat Enterprise Linux 2.1, you must install the sysstat-isag package after upgrading. Moderate Copyright 2004 Red Hat, Inc.
