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.
