"A vulnerability have been discovered in Mandriva bash package, which
could allow a malicious user to hide files from the ls command, or
garble its output by crafting files or directories which contain
special characters or escape sequences (CVE-2010-0002). This update
fixes the issue by disabling the display of control characters by
default.

Additionally, this update fixes the unsafe file creation in bash-doc
sample scripts (CVE-2008-5374).
