[***** Start RHSA-2006:0742-5 *****] Critical: elinks security update Advisory: RHSA-2006:0742-5 Type: Security Advisory Severity: Critical Issued on: 2006-11-15 Last updated on: 2006-11-15 Affected Products: Red Hat Desktop (v. 4) Red Hat Enterprise Linux AS (v. 4) Red Hat Enterprise Linux ES (v. 4) Red Hat Enterprise Linux WS (v. 4) OVAL: com.redhat.rhsa-20060742.xml CVEs (cve.mitre.org): CVE-2006-5925 Details An updated elinks package that corrects a security vulnerability is now available for Red Hat Enterprise Linux 4. This update has been rated as having critical security impact by the Red Hat Security Response Team. Elinks is a text mode Web browser used from the command line that supports rendering modern web pages. An arbitrary file access flaw was found in the Elinks SMB protocol handler. A malicious web page could have caused Elinks to read or write files with the permissions of the user running Elinks. (CVE-2006-5925) All users of Elinks are advised to upgrade to this updated package, which resolves this issue by removing support for the SMB protocol from Elinks. Note: this issue did not affect the Elinks package shipped with Red Hat Enterprise Linux 3, or the Links package shipped with Red Hat Enterprise Linux 2.1. Solution Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
