[***** Start Red Hat RHSA-2005:687-03 *****] Moderate: ethereal security update Advisory: RHSA-2005:687-03 Type: Security Advisory Issued on: 2005-08-10 Last updated on: 2005-08-10 Affected Products: Red Hat Desktop (v. 3) Red Hat Desktop (v. 4) Red Hat Enterprise Linux AS (v. 2.1) Red Hat Enterprise Linux AS (v. 3) Red Hat Enterprise Linux AS (v. 4) Red Hat Enterprise Linux ES (v. 2.1) Red Hat Enterprise Linux ES (v. 3) Red Hat Enterprise Linux ES (v. 4) Red Hat Enterprise Linux WS (v. 2.1) Red Hat Enterprise Linux WS (v. 3) Red Hat Enterprise Linux WS (v. 4) Red Hat Linux Advanced Workstation 2.1 for the Itanium Processor CVEs (cve.mitre.org): CAN-2005-2360 CAN-2005-2361 CAN-2005-2362 CAN-2005-2363 CAN-2005-2364 CAN-2005-2365 CAN-2005-2366 CAN-2005-2367 Details Updated Ethereal 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. The ethereal package is a program for monitoring network traffic. A number of security flaws have been discovered in Ethereal. On a system where Ethereal is running, a remote attacker could send malicious packets to trigger these flaws and cause Ethereal to crash or potentially execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2005-2360, CAN-2005-2361, CAN-2005-2362, CAN-2005-2363, CAN-2005-2364, CAN-2005-2365, CAN-2005-2366, and CAN-2005-2367 to these issues. Users of ethereal should upgrade to these updated packages, which contain version 0.10.12 which is not vulnerable to these issues. Note: To reduce the risk of future vulnerabilities in Ethereal, the ethereal and tethereal programs in this update have been compiled as Position Independant Executables (PIE) for Red Hat Enterprise Linux 3 and 4. In addition FORTIFY_SOURCE has been enabled for Red Hat Enterprise Linux 4 packages to provide compile time and runtime buffer checks. 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.
