   An update that fixes three vulnerabilities is now available.

Description:

   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)
