"Multiple vulnerabilities were discovered and corrected in logrotate :

Race condition in the createOutputFile function in logrotate.c in
logrotate 3.7.9 and earlier allows local users to read log data by
opening a file before the intended permissions are in place
(CVE-2011-1098).

The shred_file function in logrotate.c in logrotate 3.7.9 and earlier
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).

The writeState function in logrotate.c in logrotate 3.7.9 and earlier
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).

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:

The updated packages have been upgraded to the 3.7.9 version and
patched to correct these issues."
