Synopsis
The remote Mandriva Linux host is missing a security update.Description
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).
