Moderate: texinfo security update

New Texinfo packages that fix various security vulnerabilities are now
available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Texinfo is a documentation system that can produce both online information
and printed output from a single source file.

A buffer overflow flaw was found in Texinfo's texindex command. An attacker
could construct a carefully crafted Texinfo file that could cause texindex
to crash or possibly execute arbitrary code when opened. (CVE-2006-4810)

A flaw was found in the way Texinfo's texindex command creates temporary
files. A local user could leverage this flaw to overwrite files the user
executing texindex has write access to. (CVE-2005-3011)

Users of Texinfo should upgrade to these updated packages which contain
backported patches and are not vulnerable to these issues.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
