Updated tcl packages that fix two security issues and one bug are nowavailable for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderatesecurity impact. Common Vulnerability Scoring System base scores,which give detailed severity ratings, are available for each vulnerabilityfrom the CVE links in the References section. Tcl provides a powerful platform for creatingintegration applications that tie to gether diverse applications, protocols,devices, and frameworks. When paired with the Tk toolkit, Tcl provides a fast and powerful way to create cross-platform GUI applications. Two denial of service flaws were found in the Tcl regular expressionhandling engine. If Tcl or an application using Tcl processed aspecially-crafted regular expression, it would lead to excessive CPU and memory consumption. This update also fixes the following bug:* Due to a suboptimal implementation of threading in the current version ofthe Tcl language interpreter, an attempt to use threads in combination with fork in a Tcl script could cause the script to stop responding. At the moment, it is not possible to rewrite the source code or drop support for threading entirely. Consequent to this, this update provides a version ofTcl with out threading support in addition to the standard version with this support. Users who need to use fork in their Tcl scripts and do not requirethreading can now switch to the version with out threading support by usingthe alternatives command. All users of Tcl are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
