"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."
