Oracle Linux 6 : logrotate (ELSA-2011-0407)

This script is Copyright (C) 2013-2015 Tenable Network Security, Inc.

Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2011:0407 :

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.

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.
