medium Nessus Plugin ID 31139
Synopsis
The remote CentOS host is missing one or more security updates.Description
Updated tcltk packages that fix a security issue are now available for Red Hat Enterprise Linux 2.1, and 3.This update has been rated as having moderate security impact by the Red Hat Security Response Team.
Tcl is a scripting language designed for embedding into other applications and for use with Tk, a widget set.
An input validation flaw was discovered in Tk's GIF image handling. A code-size value read from a GIF image was not properly validated before being used, leading to a buffer overflow. A specially crafted GIF file could use this to cause a crash or, potentially, execute code with the privileges of the application using the Tk graphical toolkit.
(CVE-2008-0553)
A buffer overflow flaw was discovered in Tk's animated GIF image handling. An animated GIF containing an initial image smaller than subsequent images could cause a crash or, potentially, execute code with the privileges of the application using the Tk library.
(CVE-2007-5378)
A flaw in the Tcl regular expression handling engine was discovered by Will Drewry. This flaw, first discovered in the Tcl regular expression engine used in the PostgreSQL database server, resulted in an infinite loop when processing certain regular expressions. (CVE-2007-4772)
All users are advised to upgrade to these updated packages which contain backported patches which resolve these issues.
