"This update for logrotate provides the following fixes :

  - The shred_file function in logrotate might allow
    context-dependent attackers to execute arbitrary
    commands via shell metacharacters in a log filename, as
    demonstrated by a filename that is automatically
    constructed on the basis of a hostname or virtual
    machine name (CVE-2011-1154). (bnc#679661)

  - 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
    (CVE-2011-1098). (bnc#677336)

  - 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
    (CVE-2011-1155). (bnc#679662)

  - Fix handling of missingok option which previously was
    not working as expected."
