===================================================================== Red Hat Security Advisory
Synopsis: Moderate: logrotate security update Advisory ID: RHSA-2011:0407-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0407.html Issue date: 2011-03-31 CVE Names: CVE-2011-1098 CVE-2011-1154 CVE-2011-1155 =====================================================================
1. Summary:
An updated logrotate package that fixes multiple security issues is now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
3. Description:
The logrotate utility simplifies the administration of multiple log files, allowing the automatic rotation, compression, removal, and mailing of log files.
A shell command injection flaw was found in the way logrotate handled the shred directive. A specially-crafted log file could cause logrotate to execute arbitrary commands with the privileges of the user running logrotate (root, by default). Note: The shred directive is not enabled by default. (CVE-2011-1154)
A race condition flaw was found in the way logrotate applied permissions when creating new log files. In some specific configurations, a local attacker could use this flaw to open new log files before logrotate applies the final permissions, possibly leading to the disclosure of sensitive information. (CVE-2011-1098)
An input sanitization flaw was found in logrotate. A log file with a specially-crafted file name could cause logrotate to abort when attempting to process that file a subsequent time. (CVE-2011-1155)
All logrotate users should upgrade to this updated package, which contains backported patches to resolve these issues.
4. Solution:
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259
