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

    [3.7.8-12.1]
    - fix #688518 - fixed CVE-2011-1154, CVE-2011-1155       and CVE-2011-1098

Tenable has extracted the preceding description block directly from the Oracle 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.

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)

The remote host is affected by the vulnerability described in GLSA-201206-36 (logrotate: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in logrotate. Please       review the CVE identifiers referenced below for details.
  Impact :

    A local attacker could use this flaw to truncate arbitrary system file,       to change file owner or mode on arbitrary system files, to conduct       symlink attacks and send arbitrary system files, to execute arbitrary       system commands, to cause abort in subsequent logrotate runs, to disclose       sensitive information, to execute arbitrary code or cause a Denial of       Service condition.
  Workaround :

    There is no known workaround at this time.

This update for logrotate provides the following fixes :

  - Race condition in the createOutputFile function in     logrotate allows local users to read log data by opening     a file before the intended permissions are in place.
    (bnc#677336 / CVE-2011-1098)

  - The writeState function in logrotate might allow     context-dependent attackers to cause a denial of service     (rotation outage) via a (1) \n (newline) or (2) \     (backslash) character in a log filename, as demonstrated     by a filename that is automatically constructed on the     basis of a hostname or virtual machine name. (bnc#679662     / CVE-2011-1155)

It was discovered that logrotate incorrectly handled the creation of new log files. Local users could possibly read log files if they were opened before permissions were in place. This issue only affected Ubuntu 8.04 LTS. (CVE-2011-1098)

It was discovered that logrotate incorrectly handled certain log file names when used with the shred option. Local attackers able to create log files with specially crafted filenames could use this issue to execute arbitrary code. This issue only affected Ubuntu 10.04 LTS, 10.10, and 11.04. (CVE-2011-1154)

It was discovered that logrotate incorrectly handled certain malformed log filenames. Local attackers able to create log files with specially crafted filenames could use this issue to cause logrotate to stop processing log files, resulting in a denial of service.
(CVE-2011-1155)

It was discovered that logrotate incorrectly handled symlinks and hard links when processing log files. A local attacker having write access to a log file directory could use this issue to overwrite or read arbitrary files. This issue only affected Ubuntu 8.04 LTS.
(CVE-2011-1548).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
