Description

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.
