RHSA-2011:0407 - Moderate: logrotate security update

Synopsis

Moderate: logrotate security update

Type/Severity

Security Advisory Moderate

Topic

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.

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.
