## Description

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.
