RHEL 6 : logrotate (RHSA-2011:0407)

Synopsis

The remote Red Hat host is missing one or more security updates for logrotate.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2011:0407 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL logrotate package based on the guidance in RHSA-2011:0407.
