RHSA-2011:0407 - Security Advisory

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.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
