Detail
Problem Description: Updated tcl packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Description: Tcl (Tool Command Language) provides a powerful platform for creating integration applications that tie together 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 expression handling engine. If Tcl or an application using Tcl processed a specially-crafted regular expression, it would lead to excessive CPU and memory consumption. (CVE-2007-4772, CVE-2007-6067) This update also fixes the following bug: * Due to a suboptimal implementation of threading in the current version of the 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 of Tcl without threading support in addition to the standard version with this support. Users who need to use fork in their Tcl scripts and do not require threading can now switch to the version without threading support by using the alternatives command. (BZ#478961) All users of Tcl are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 316511 - CVE-2007-4772 postgresql DoS via infinite loop in regex NFA optimization code 400931 - CVE-2007-6067 postgresql: tempory DoS caused by slow regex NFA cleanup 478961 - [RHEL5] tcl threads support implementation can cause scripts to hang |
