A local attacker could use this flaw to truncate arbitrary system file,
to change file owner or mode on arbitrary system files, to conduct
symlink attacks and send arbitrary system files, to execute arbitrary
system commands, to cause abort in subsequent logrotate runs, to
disclose sensitive information, to execute arbitrary code or cause a
Denial of Service condition.
